With 24 goals in 23 games this season, the Gabon international is the leading scorer in the Bundesliga at the winter break. Former coach Jurgen Klopp would like him at Liverpool, but it is worth noting that Aubameyang is under contract until 2020 and the player has recently stated how happy he is at Dortmund.
PIERRE-EMERICK AUBAMEYANG (26, striker) Borussia Dortmund
Linked with: Liverpool, Manchester City, Manchester United
MICHY BATSHUAYI (22, striker) Marseille
Linked with: Arsenal, Crystal Palace, Tottenham
The Belgian has graduated from super sub last season to focal point this time around after the departure of Andre-Pierre Gignac. At the age of only 22, he is likely to make the Belgium Euro 2016 squad and has scored in both of his appearances for his country so far. Only PSG striker Zlatan Ibrahimovic has netted more goals than Batshuayi in Ligue 1 this season.
LARS BENDER (26, midfielder) Bayer Leverkusen
Linked with: Arsenal
Manager Arsene Wenger has a holding midfielder on his radar following the injury to Francis Coquelin. The German international - the twin of Borussia Dortmund player Sven - has played in the Champions League this season and is solid and dependable.
ASHLEY COLE (35, defender) Roma
Linked with: Aston Villa, Crystal Palace
Since joining Roma in 2014, left-back Ashley Cole has been on the fringes of the squad - literally
Cole has had such a bad time in Italy that his club could agree to cancel his two-year contract a season ahead of schedule. The former England left-back made just 11 appearances for the Serie A side last season and hasn't played a single game this term. He could surely do a decent job for someone in the Premier League, if they can get him fit. A short-term signing worth considering.
ANWAR EL GHAZI (20, winger) Ajax
Linked with: Liverpool, Manchester United, Southampton, Stoke
Dutch football is down in the dumps but El Ghazi is the kind of player who can cheer the fans up again. He made his senior Netherlands debut late in 2015 and many more caps are expected. Only a matter of time before he moves to a bigger club, possibly in the Premier League.
GONZALO HIGUAIN (28, striker) Napoli
Linked with: Arsenal, Chelsea
Gonzalo Higuain in action for Napoli
"HI-GUA-IN! HI-GUA-IN!" The in-form Argentine striker is enjoying a very successful season with Napoli
One of the world's top forwards at the moment, Higuain would give Chelsea the cutting edge they have lacked because of Diego Costa's loss of form. Higuain has two-and-a-half years left on his contract and a bid of £50-60m could perhaps tempt Napoli to sell.
TERENCE KONGOLO (21, defender) Feyenoord
Linked with: Manchester United, Southampton
After progressing from the well-regarded Feyenoord academy, Kongolo was given his debut in April 2012 by Ronald Koeman - who has been linked with a move to take him to Southampton. The defender is part of the Netherlands' rebuilding plans for the coming years and has also been scouted by Manchester United.
DIRK KUYT (35, striker) Feyenoord
Linked with: Barcelona
Yes, it might be surprising, but stranger things have happened. The Dutchman has had a new lease of life after returning to his homeland. Second highest scorer in the Eredivisie this season with 13 goals, Kuyt could head to the Nou Camp with Barcelona looking for an experienced forward to act as back-up to Lionel Messi, Neymar and Luis Suarez.
GRZEGORZ KRYCHOWIAK (25, midfielder) Sevilla
Linked with: Arsenal
The Pole has been watched regularly by the Gunners, whose need for a defensive midfielder has increased since Coquelin damaged knee ligaments in November. Krychowiak has been a key man for the back-to-back Europa League winners.
RAVEL MORRISON (22, winger) Lazio
Linked with: QPR
Will anyone take him now? Morrison ran out of chances at Manchester United, blew it at West Ham and has not settled at Lazio, either. He is desperate to return to England in January although his baggage - fined for criminal damage, a caution for common assault and admitting two counts of witness intimidation - might dissuade most clubs.
RUBEN NEVES (18, midfielder) Porto
Linked with: Arsenal, Chelsea, Liverpool
A regular in the Porto side as well as taking the captain's armband at his tender age, Neves is already a Portugal international and looks destined for the top. Suitors have been attracted from the Premier League but will have to shell out big money to sign him up.
NOLITO (29, winger/striker) Celta Vigo
Linked with: Arsenal, Barcelona
The Barcelona youth product is having the season of his life and playing so well that his old club have apparently thought about taking him back. Arsenal have been linked, too, but they're not exactly short of wide attackers, and Nolito will be 30 in October.
MARTIN ODEGAARD (17, midfielder) Real Madrid
Linked with: Celtic, Getafe, Rayo Vallecano
Everyone wanted to sign Martin Odegaard but he has so far been out in the cold at Real Madrid
Norwegian starlet Odegaard has failed to make an appearance under Rafael Benitez this season and the teenager needs minutes to continue his development. A loan move is more likely than a permanent one.
ADRIEN RABIOT (20, midfielder) Paris St-Germain
Linked with: Arsenal, Juventus
The young Frenchman has said he wants to leave the club on loan in January, despite featuring quite often for the Ligue 1 leaders this season. Is a place in the squad for Euro 2016 playing on the mind of the France Under-21 international?
SANDRO RAMIREZ (20, forward) Barcelona
Linked with: Tottenham
A supremely talented young player, but unlikely to have regular football at Barcelona any time soon. Tottenham head coach Mauricio Pochettino reportedly admires Sandro and the north Londoners are following him closely. Leaving Barca might mean never returning - would Sandro take that risk?
ARJEN ROBBEN (31, winger) Bayern Munich
Linked with: Manchester United
The Dutchman's season has been disrupted by injury, but he has still managed five goals in 12 games for the Bundesliga leaders. With Manchester United's need for pace in the wide areas, he could well be the marquee signing Louis van Gaal needs for his side.
LEROY SANE (19, midfielder) Schalke
Linked with: Liverpool
Few countries are better than Germany at producing high-class midfielders - and Sane is the latest. Even though he has made only a handful of appearances for Schalke, Sane has already earned a full cap for the national side and Jurgen Klopp is a firm admirer.
ISLAM SLIMANI (27, striker) Sporting Lisbon
Linked with: Crystal Palace
Sporting are trying to win the Portuguese title and it is thought they would demand at least £14m to sell the Algerian in January. The price is likely to drop in the summer, but Palace boss Alan Pardew might decide to take a gamble in order to strengthen the club's chase for a European spot.
GOKHAN TORE (23, winger) Besiktas
Linked with: West Ham
Slaven Bilic worked with the Turkey international at Besiktas and it is believed he would like to bring him to Upton Park. Tore is quick, direct and aggressive and should do well in England - but top clubs in Turkey are cash-rich and Besiktas could tempt Tore to stay.
SIMONE ZAZA (24, striker) Juventus
Linked with: Crystal Palace, Watford, West Ham
After two excellent seasons at Sassuolo, Zaza has struggled to cement his place in the Juve first team and could leave Turin, initially on loan. He has won seven caps for Italy but there are doubts about whether his style of play is suited to the English game.
