Last January, Chelsea sold Juan Mata to Manchester United for £37m, as well as offloading Kevin De Bruyne to Wolfsburg for £18m.
A year on, Wolfsburg appear set to attempt another swoop on the Blues, with reports suggesting that they have made a €30m (£24m) bid to sign Andre Schurrle.
Schurrle, 24, joined Chelsea from Bayer Leverkusen back in 2013, with the Blues forking out around £18m to bring the German international to Stamford Bridge.
Whilst he was far from first choice last season, Schurrle managed to score eight goals in 30 Premier League appearances, even if he was somewhat in the shadow of Eden Hazard, Oscar and Willian in Jose Mourinho's 4-2-3-1 system.
Schurrle is again in and out of the side, and has started just five games this season, though a return of two goals is fairly impressive.
Now, Chelsea will have a decision to make. Fans want Mourinho to sign a new right winger anyway, and the money from selling Schurrle could be put towards such a pursuit.
Yet Schurrle's versatility comes in handy. Able to play out wide, behind a striker or even up front on his own, Schurrle has become a decent option for Mourinho to use in big games thanks to his tactical awareness and work rate.
It's a tempting offer for Schurrle, but Chelsea need to have a replacement lined up before they consider selling a player who is so trusted by Mourinho.
