Alan Shearer has warned Chelsea frontrunner Liam Rosenior he must surpass Enzo Maresca's achievements if he it to survive at a 'bonkers' club.
Rosenior has been viewed the leading contender to succeed Maresca at Stamford Bridge following the Italian's shock New Year's Day departure.
The 41-year-old currently coaches Strasbourg, with the Ligue 1 side also run by Chelsea's owners BlueCo.
Former Newcastle and England forward Shearer admitted that Maresca's exit had come as a surprise, but suggested he had intensified speculation over his future by claiming he had experienced his 'worst 48 hours' at the club in December.
