The EPL will always have this competitive disadvantage:
Diego Costa:
"I wished I could go back to Atletico, I'm not going to lie," he told Spanish TV station Movistar Plus while on international duty.
"Everyone knows what happened to me in England, with the language, the weather and everything. But I can't complain because I'm a boy whom the fans love, at Chelsea they respect me.
"I had the chance to go back but I couldn't, because of a few details. I'm grateful to the people at Atletico, to Cholo [Simeone] especially, who has always put his confidence in me.
"Now I am at Chelsea, I'm doing well, the league has started and I'm focused on that. Things are how they are. I hope that Atletico do very well, like last season but this time win titles. I want the best for them, I always feel for them, but I have to do my work at Chelsea."
Costa was part of the Atletico side that won the 2013-14 La Liga title and reached the 2014 Champions League final under Simeone, while he won the league in his first season in England.
