Chelsea have been a constant threat to Atlético Madrid over the past few seasons off the pitch. Last summer the Premier League club took Diego Costa and Filipe Luis to Stamford Bridge and tried to lure Thiago as well, although the Portuguese midfielder elected to remain at the Calderón. Costa had a good first season in English football while Filipe hardly got a kick and returned to Madrid this summer, although he is not the same player he was during his first spell at Atlético.
Relations between Chelsea and Atlético have always been cordial but things soured a little when Thibaut Courtois was called back to London after three seasons on loan at Atlético. The Belgium keeper played an instrumental part in Atlético's league title success and Diego Simeone wanted to secure his services for another season at least.
Now, Chelsea are expected to return to the Calderón to reinforce their squad again. The players being watched by the Premier League champions are key ones for Simeone: Diego Godín, Koke and Antoine Griezmann. However, Atlético have moved to ward off Chelsea's interest – and that of other European clubs – by offering the players improved contracts, with pay rises and a significant increase in their buy-out clauses. Godín and Koke have signed on until 2019 and Griezmann until 2020.
Meanwhile, Roman Abramovich is reportedly interested in acquiring the services of Simeone. UK reports have stated that Chelsea are prepared to pay the 20 million euros it would cost to release Simeone from his contract at the Calderón in the case that José Mourinho ceases to manage at Stamford Bridge.
Atlético never make any public statements regarding their manager but one thing is clear within the club: Simeone will not be going anywhere before the end of the current season. The Argentinean has a contract until 2020 and has not expressed any desire to seek pastures new.
