New interim Chelsea boss Guus Hiddink has told fans not to expect a quick fix to the club's recent problems.
Hiddink, 69, takes charge of his first game against Watford on Saturday, having watched from the stands as the Blues beat Sunderland 3-1 after the departure of Jose Mourinho last week.
The Dutchman has returned to Stamford Bridge after leading Chelsea to the FA Cup in 2009, but admitted he can't just walk in and change everything around immediately.
"If you look back a bit to last season where there was this huge success in winning the title then of course you go into the next season and you have your targets, your aims and your aims are the same," he said.
"Getting the championship again, even though in the Premier League that is not easy, that was the main target. The other targets of course are to go into the Champions League and the FA Cup.
"But it is not easy to fix as sometimes after a championship you might relax a bit as a team and then you get a wake-up call from somewhere in September, but the situation is that they were down last week to one point off the relegation zone, which was frightening for everyone inside the club.
"It is not easy to say 'I am here and tomorrow the problem is solved'."
