5 players who could sign for their former clubs in the summer transfer window

#4 Diego Costa – Chelsea to Atletico Madrid

Costa has been an unsettled figure at Chelsea since arriving from Atletico Madrid.

One of the reasons that has led to Chelsea intensifying their interest in Romelu Lukaku is the speculation that surrounds their own marksman Diego Costa. The Spaniard has put behind a troubled last season and currently looks as fit and sharp as he has ever been and has played a pivotal role in helping his side climb atop the Premier League table.

However, the Spaniard does not look entirely happy in England, especially with the added media glare and has made it known in the past that he would love to move back to Atletico Madrid, the club where he truly made a name for himself as a striker.

The Spanish international, who has scored 18 goals across all competitions this season was believed to be a subject of a big money transfer bid from an undisclosed Chinese club in the winter transfer window. However, at 28 years of age, it might be too early to be moving to the Chinese Super League.

Costa moved to Chelsea in 2014 from Atletico Madrid

While the player has recently confirmed that Atletico did not heed to his requests to take him back, the Madrid club might be forced to re-sign him in the upcoming transfer window.

Antoine Griezmann looks destined to move to a bigger club following his exploits at the Vicente Calderón Stadium as well as with the French national team and Costa, who has already shown an ability to thrive in Spanish conditions would be the perfect replacement for the French superstar.
