"Atletico" left-back Filipe Luis's agent confirmed that London's "Chelsea" is interested in his client's services.
Recent reports in England have suggested that the "Blues" are closing in on an agreement with the Brazilian, and "Los Rojiblancos" forward Diego Costa is also expected to arrive in London.
However, F.Luis's agent Garcia Quilon warned "Chelsea" that acquiring the defender will not be easy, as "Atletico" is reluctant to sell any of their players.
"There is interest, but 'Atletico' does not want to sell Filipe Luis," said the agent regarding Chelsea's interest.
"They want every player to stay in the team, but we will have to wait until the end of the summer. 'Atletico' is not ready to let go of any player," added G.Quilonas.
F.Luis has been playing for the Madrid team since 2010, when he arrived from the "Deportivo" club in La Coruna. This season, the defender appeared in 48 matches and scored one goal.
