Jose Mourinho is calling on his squad to find their killer instinct ahead of what is likely to be a six-way fight for the Premier League title.
The Chelsea boss says that as of yet, he has been unable to instil the required mental strength among the current group of players and has called on them to use Didier Drogba and Zlatan Ibrahimovic as their inspiration.
Mourinho says the two strikers, who he managed at Chelsea and Inter Milan respectively, were head and shoulders above the rest when it came to handling pressure.
He wants his current crop of stars to match that intensity.
"I like to put pressure on them, yes, but you have to analyse the players you're working with," he is quoted as saying in the Daily Mirror.
"I gave Didier as an example. When I put real pressure on him, the animal was always coming out.
"Ibrahimovic at Inter - exactly the same. When I put real pressure on him, I knew that the answer was coming.
"It depends on the players' profiles. Some react in a very good way. Some don't. I have players who have told me not to criticise them in front of the other guys because, 'It's not good for my self-esteem.' I've had everything."
Mourinho has admitted that he believes the fight for the title could be as open as ever and believes Chelsea players must see the struggle to become champions as a positive thing.
He added: "One of the things is to make the pressure of fighting for the title to be something natural, something that players accept in a positive way, not in a negative way.
"We have here some people who won the title before, but they've not won it for quite a long time. When you don't do that for quite a long time, you forget it.
"We've also got players who were playing in clubs not used to fighting for titles, clubs who'd do fantastic one day and see what would happen the next.
"That pressure to try and be top of the league, knowing that every little detail and every point can make a difference."
Despite admitting it is an open title race, The Special One admitted the main rival to the Stamford Bridge outfit is Manchester City.
He said: "The squad is absolutely amazing. They have solutions and solutions and solutions.
"If you ask me which team has more ammunition, I have to try and be honest. I have to apologise to the others in case they're not happy with what I say, but City are the team with more ammunition."
