Chelsea goalkeeper Petr Cech feels the squad need only minor tweaks to be transformed into Premier League contenders.
Cech, 31, reckons Jose Mourinho will be inheriting a special squad.
He said: "We have many talented players, having won two European trophies, some FA Cups and the Double.
"I think that he gave us a lot of experience, so in a way he will find an interesting team to come back to.
"In a big club, you always have the same expectation, no matter who the manager is. The players always want to win everything, so the pressure won't be any different.
"He might come with a slightly different way than last time, let's see. But it will be great to see him back and hopefully he can reproduce the success we had last time."
