Chelsea striker Diego Costa will return to Atletico Madrid, according to reports from Spain.
On Monday, Marca reported that the 26-year-old failed to settle down in London and is desperate to return to the Spanish Liga.
"Although he has had a successful season with Mourinho and Co., Diego Costa is not happy at Chelsea," the report says.
"The problem is that he has not settled in London - the wet English climate, the language, the food.
"All these are key factors in Costa having contacted the Atletico de Madrid board - with whom he enjoys an excellent relationship - with a view to coming home, to the club he joined at the age of 17 and where he was a big star by the age of 25.
"The player is even prepared to take a drop in salary. When he went to Chelsea he earned double what he got at Atletico, almost €7 million per season net, and he knows full well that Atletico de Madrid cannot match that."
In his first year at the club, the Spaniard scored 20 goals in 37 games and boss Jose Mourinho has identified Napoli striker Gonzalo Higuain as the one to register the same number of goals next season.
Arsenal are Manchester United are also interested.
The former Real Madrid man scored twice against Lazio on Sunday but failed to score from the spot as the Partenopei failed to secure a Champions League place for next season.
And with no Champions League football, the 27-year-old will surely leave Italy with the Premier League an option.
