Chelsea owner Roman Abramovich is eyeing up Atletico Madrid boss Diego Simeone as a replacement for Jose Mourinho, as reported by the Mirror.
The 45-year old Argentine has impressed Russian billionaire Abramovich during his time in charge of the Madrid giants, after he won the La Liga title and reached the Champions League final.
With the Blues struggling 16th place, Mourinho is understood to be aware of Chelsea’s succession plan should he fail to steer the club back up to the highest echelons of the Premier League.
The Atletico Madrid boss has managed to keep the club competitive despite the vast fortunes of both Real Madrid and Barcelona, and was mere seconds away from a Champions League final victory in 2014.
He has also won the Europa League and the Copa Del Rey, with the latter coming against Mourinho when the Portuguese was in charge of Real Madrid.
However, Simeone is understood to have a £15m buyout clause in his deal in the Spanish capital, as he signed a five-year extension earlier this summer.
Mourinho was rewarded with a four-year contract after guiding the club to a first Premier League title in five years back in May, though has struggled to replicate such good form at all this term.
