Chelsea coach Steve Holland has likened Kevin de Bruyne to Oscar.
De Bruyne enjoyed an outstanding season on-loan at Werder Bremen.
Holland told chelseafc.com: "He started the season playing in a central attacking role, where he could get forward but also be disciplined. Towards the end of the season he played behind the striker and then finished on the wing, so he's had experience of a few roles, which will stand him in good stead.
"He's a bit like Oscar, in that he's played in a range of attacking positions. A lot of German clubs have been very impressed with him, he played almost every minute of every game for Bremen, he had a good impact and will be ready to push on."
