With Borussia Dortmund striker Robert Lewandowski's contract set to expire at the end of the season, he could be sold this January for just £7m, leaving Jurgen Klopp with just Pierre-Emerick Aubameyang and Julian Schieber as the only recognised forwards.
Here are five players last season's Champions league finalists could look to replace the Pole with:
1) Javier Hernandez
Manchester United's Mexican striker has proved in his time in England to be a top quality player. Despite this, he has struggled to pin down a regular starting place for the champions due to the competition of Robin van Persie and Wayne Rooney.
But in the pitch time the 'Little Pea' has received, he has been a valuable asset, scoring important goals and has the ability to be the number one striker at Dortmund with his pace, clever movement and clinical finishing. He may be content with his situation at Old Trafford but could his head be turned by an opportunity at Dortmund to be Jurgen Klopp's main forward.
2) Karim Benzema
Benzema is struggling to please the Madridstas at the moment, even though he has a fairly respectable goalscoring record.
In the summer, it was Benzema and not Gonzalo Higuain who managed to stay in the Spanish capital and the fans have been keen to see more of their young talent, Alvaro Morata.
With pressure growing on Benzema and as Madrid are continually linked with Liverpool's Luis Suarez, an escape to Dortmund could be something the Frenchman might warm to. However the price tag Madrid would want might be a stretch too far for the Germans.
3) Luis Muriel
The Colombian striker is playing in Serie A with Udinese and scored an impressive eleven times last campaign despite injury. The powerful striker is blessed with great pace and is deadly in front of goal.
He could be an ideal replacement for Lewandowski and at 22 years of age has great potential. He may have only recently signed a new deal with the club, running until 2018, but at the correct price, Udinese could be willing to sell.
4) Demba Ba
The 28-year-old is out of favour at Jose Mourinho's Chelsea, with Fernando Torres and Samuel Eto'o receiving more game time.
Ba was prevented a loan move to Arsenal in the summer due to them being direct rivals, but Dortmund of course are not. Therefore the move could go ahead and the Senegalese striker has previously played in Germany for Hoffenheim, where he scored regularly before moving to West Ham United.
5) Lukas Podolski
The German is in his second season at Arsenal and is currently sidelined with injury. Last season he managed eleven Premier League goals for the Gunners and has two so far this campaign.
The 28-year-old has had spells with Bayern Munich and FC Koln in the Bundesliga and could be interested in a third crack of the whip. Arsene Wenger has used the striker in a wide-left role as he has played for Germany but a central opportunity at Dortmund might be attractive if an offer were to emerge. Though Podolski may be concentrating on a longer run in England.
