The Brazil international has spoken of his admiration for Jose Mourinho.
Chelsea are looking to rejuvenate their attack this summer and have been linked with a whole host of targets in recent weeks. Among those potential arrivals is Douglas Costa, and the 24-year-old attacking midfielder seems open to a move to Stamford Bridge.
After six successful years at Shakhtar Donetsk, Costa seems ready for a change of environment.
"Eventually the time comes when you get tired of playing always in the same league. I'm 24 years old and it is worth trying to tell people that I want to go," he revealed in an interview with The Express.
He also took the opportunity to specifically praise the Chelsea boss, adding: "We have a wonderful coach in Mircea Lucescu, but I think it's time for a change and I think Mourinho is the best in the world."
Flattery can go a long way and if Douglas Costa gets his wish, it could take him all the way to West London.
He would add to Chelsea’s significant Brazilian contingent but it’s not clear how much of an upgrade he would be on the current crop. Managing only 37 goals in 196 appearances for Shakhtar, he is hardly prolific. Blessed with pace and strong dribbling ability, he can torment defences on his day but much like a fellow ex-Shakhtar Brazilian at Chelsea - Willian – the end product isn’t always there.
