Chief executive Peter Kenyon insists Chelsea's hunger for success will not cost manager Jose Mourinho his job.

Kenyon says Chelsea owner Roman Abramovich's long-term plans for the Blues include Mourinho at the helm.
He said: "There's loads of speculation that if we don't win Jose gets fired, but that's not the way we think.
"It's about winning in style and building that dynasty, and that's what Roman wants to be part of; Chelsea becoming part of Europe's dynasty."
Former Manchester United chief executive Kenyon revealed Chelsea's desire to become a worldwide brand in the same manner as his former employers.
Kenyon said: "Over a 10-year period, you need two European Cups to be a world club, and you have to dominate your domestic league.
"We have an infrastructure to deal with that and people to deal with it.
"We will win the Champions League, the question is when," Kenyon says in the Chelsea documentary Blue Revolution.
"We've got a squad, a structure, a belief and we've got quality; I believe the Champions League is not far away."
Kenyon also claims Mourinho is the most similar manager to Manchester United boss Sir Alex Ferguson he has yet seen.
After joining Chelsea in 2003, Kenyon was instrumental in bringing former Porto boss Mourinho to Stamford Bridge to succeed Claudio Ranieri.
The Chelsea chief executive said: "After the first week I didn't feel Ranieri was up to the job. Having been around a winner like Sir Alex, Ranieri certainly didn't come into that class, so we embarked on looking for a new manager.
"We came up with Mourinho who was young and different.
If we win, we want to win stylishly, everyone buys into that

"We'd seen some of the best names but he was hungry and thought differently and I saw he had some of the same qualities as Alex Ferguson.
"He's a winner and we were lucky enough to get him, and I think we've had some success since then."
Kenyon also revealed that Abramovich has concerns about Chelsea's on-field image, and that the Russian billionaire is keen to couple success with style.
"He's passionate about Chelsea; he's passionate about how we are perceived, how we do things. If we win, we want to win stylishly, everyone buys into that.
"He's the best possible thing that could have happened to Chelsea," added Kenyon.
"He's thoughtful, he's strong and he's been a very successful businessman. But he's very different to how anybody would portray him because nobody knows him."
