Atletico Madrid are already preparing for the departure of Diego Costa, sending scouts to search for potential replacements, reports French newspaper Le 10 Sport.
The Brazilian-born striker has been in excellent form for the La Liga outfit, making up for the loss of Radamel Falcao and firing them towards a genuine title challenge.
So far the player has scored 21 goals in 24 league games, just one less than Ballon d'Or holder Cristiano Ronaldo, attracting interest from a number of Premier League clubs.
Arsenal and Chelsea are named as the most interested parties by the French publication with both Jose Mourinho and Arsene Wenger keen to add quality to their attacking line-ups.
Samuel Eto'o looks set to leave Stamford Bridge following Mourinho's comments about the player's age while Nicklas Bendtner is likely to depart the Emirates.
Chelsea could also see Demba Ba leave, making room for a world class addition like Diego Costa.
And it seems that Atletico are already preparing for Costa departure and have sent scouts across Europe searching for potential replacements.
Costa is believed to have a release clause of £32m installed into his contract and Atletico are expecting a club to meet it.
One potential replacement highlighted by Le 10 Sport is Manchester City's Edin Dzeko, who is struggling to get game time at the Etihad and could be available in the summer.
