Former Chelsea boss Avram Grant has warned successor Luiz Felipe Scolari that he is embarking on an impossible job at Stamford Bridge.
Scolari was confirmed as the replacement for the sacked Grant last month with the Brazilian officially taking the reins on July 1 following his decision to step down as coach of the Portugal national side.
But Grant has warned the incoming Blues boss that he is on a hiding to nothing after he was axed after just nine months at the helm.
The Israeli was shown the exit door after losing the Champions League Final on penalties to Manchester United just days after being confirmed as runners-up in the Premier League.
"I like Scolari very much, as a person and coach," Grant said in the Daily Mail. "I wish him the best of luck.
"But he will soon realise he has his work cut out. He will do well to match what I did last season and even that was not enough to keep me in the job."
Meanwhile, the Blues continue to be linked with a move for Russia star Andrei Arshavin.
The 27-year-old playmaker is expected to join one of Europe's leading clubs after starring during Euro 2008.
Reports claim Chelsea's Russian owner Roman Abramovich is desperate to lure him to London from Zenit St Petersburg in a £20million deal.
