6 high-profile stars who need to go out on loan this season

#4 Chelsea - Diego Costa

Diego Costa's antics may have cost him his Chelsea career

That Diego Costa is leaving Chelsea is certain.

What's not certain is when - it's no secret that Diego Costa is desperate to leave and go back to Atletico Madrid, having even been pictured in a Rojiblancos jersey on a live social media broadcast. However, Atletico have been hit with a transfer ban and can only register players in January.

In another year, Costa would have moved to Atletico in the summer, kicked back for 6 months and begin playing from January. However, Costa risks his place in the 2018 FIFA World Cup squad for Spain, with fierce competition expected from Alvaro Morata, ironically at Chelsea.

Costa can increase his chances by making a loan move to a Premier League team in London, such as West Ham or even Crystal Palace - the player is clearly too good for the clubs in question, but his international career is at stake.
