West Ham boss Slaven Bilic is confident West Ham can inflict a fourth defeat on Chelsea when they both clash in Saturday's London derby at Upton Park. He however believes Jose Mourinho is still the best manager in the Premier League despite Chelsea's struggles.
Former Besiktas boss Bilic has impressed in the opening months of the season at Upton Park, guiding the club to fourth in the table, having orchestrated impressive away wins at Arsenal, Manchester City and Liverpool.
The Hammers have however struggled at home to match their impressive away record, winning once against Newcastle United, drawing one and losing to AFC Bournemouth and Leicester City.
"This is a good time to play Chelsea, but they need to have a few good results," Bilic said in Thursday's news conference.
"Chelsea looked sharp against [Dynamo] Kiev and I watched the game [a 0-0 Champions League draw].
"I was not happy afterwards because they looked really good as a team.
"It is a big challenge for us and a big test. It is not me against [Jose] Mourinho, it is West Ham against Chelsea.
"They are the champions and he is the best manager around. I am looking forward to it.
"I know Mourinho's team are always hungry and no-one expected them to be where they are now. Sometimes that happens in football.
Bilic however tipped Chelsea to finish in the top four despite their poor start in the EPL.
"I have watched all their games. If there was something major wrong he would be the first to change it. I see them finishing in top four."
