Costa finished as Chelsea’s top scorer for each of his three seasons in London, but while his contribution on the field was huge his time at Stamford Bridge has not always been harmonious.
In his second season his sudden loss of form was a contributory factor in the poor start to the campaign which ended in the sacking of coach Jose Mourinho.
After winning a second Premier League winners’ medal last season he made clear his wish to rejoin Atletico during the summer after claiming Chelsea manager Antonio Conte had told him via text message that he was no longer required at the club.
Problems arose at the start of the year when Costa was left out of the Chelsea side for an away match at Leicester City after reports of a training ground dispute with a fitness coach.
