Jose Mourinho will have a summer filled with more questions than answers despite his side winning the Premier League this season.
Whilst a fair amount of the squad at Stamford Bridge will stay the same, there will be a cohort of players leaving the club, opening the door to new singings for the West London club.
One such potential singing will already sound familiar to Chelsea fans. Douglas Costa could be set to link-up with the club after his trip to Chile to play in this years Copa America.
Costa started his career at Germio before moving to Shakhtar in 2010 and has had a very successful time in his spell at the club, winning several trophies including at domestic treble in the 2010/11 season.
The 24-year-old has made his name as one of the quickest and most creative players in Europe. His ability to run at pace with the ball and beat a man make him a tantalising prospect for the Blues.
Chelsea have also struggled to find a consistent free-kick taker since the departure of Juan Mata, a hole Douglas would fill with ease. The winger has scored 39 career goals and would have to compete with the likes of Willian, Hazard and Cuadrado if he were to find a place in Mourinho’s side this summer.
The left footed winger will remind many onlookers of Bayern Munich’s Arjen Robben. The wide man often looks to cut inside onto his left foot. Set the ball outside of the far post, and bend it back into the top corner.
Costa will be looking to register his first international goal at this years Copa America and to start his Brazil career off with a bang. His next game for his country will only be his third cap.
