As Chelsea look to become a genuine Premier League force once again, their transfer market activity is being watched with eagle-eyed interest.
Antonio Conte is attempting to right the wrongs of Jose Mourinho's shambolic final six months at the helm and has already spent hefty sums on Michy Batshuayi and N'golo Kante. Chelsea's mission for the new season must be to, at the very least, compete for top four football.
The mess to be cleared up is substantial, from lawsuits to unfit stars, Chelsea are beginning on a long road to recovery and the remainder of this transfer window will dictate the potential that Conte's team have ahead of the new season.
Conte is preparing to wield Abramovich's chequebook once again, looking to fill the final slots in his squad. Where should he target? Does he need a defender? Another forward? A full-back?
In any case, we've got a nifty list of THREE stars Chelsea could sign from German super club, Borussia Dortmund...
Pierre-Emerick Aubameyang
Strikers don't come much better than Aubameyang in world football. The Gabonese forward has come on leaps and bounds since his transfer from Saint-Etienne and returned 25 goals for Dortmund last season.
It is easy to hone in on his electric pace, but Aubameyang is more than that. His runs are intelligent, his finishing lethal and there are few harder players to mark in the European game.
Chelsea, despite the arrival of Batshuayi, are still in the market for another forward and Aubameyang would be perfect. With Loic Remy likely to move on from the club this summer, Aubameyang would be an infinite improvement.
Mattias Ginter
Chelsea need a centre-back and a right-back. Mattias Ginter is one way to kill two defensive birds with one stone. The 22-year-old German has been a rock at the heart of the Dortmund defence and shown his versatility by slotting in as a number six on occasion.
The Blues are in desperate need of defensive reinforcements, the hard-tackling Ginter could be just the man they've been looking for. Whether used as a long-term partner for Kurt Zouma or as the replacement for Branislav Ivanovic, Ginter would be a truly special signing for Chelsea.
Julian Weigl
It looks increasingly likely that one of Nemanja Matic or John Obi Mikel will leave the club this summer and that might trigger Antonio Conte to invest in another defensive midfield player.
N'golo Kante is likely to play in a more free-roaming ball-winning role, leaving Conte without a natural deeper defensive midfielder.
Weigl, who can play in a number of midfield roles, is an excellent reader of the game. He averaged 2.1 interceptions per Bundesliga fixture last season and would be the ideal third man in a Chelsea midfield alongside Kante and Fabregas.
