Chelsea assistant Steve Holland has urged the clubs players to place all their trust in manager Jose Mourinho.
The Portuguese tactician has come under fire for rarely using Juan Mata in the early stages of this season but Holland suggests the boss has what it takes to turn teams, as well as individuals such as Real Madrid ace Cristiano Ronaldo, into top quality assets.
"He (Mourinho) is always pushing, pushing the players to the maximum every day," said Holland. "That's evident not just in his teams, but in the individuals he's worked with.
"If you look Jose's three-year period working with Ronaldo, he's really evolved as an individual. He's not just a talented dribbler and runner with the ball who can score goals.
"He has become a top-level match-winner who wants to run in behind, make runs, threaten the goal.
"I don't think that just happens. That comes with pushing, even if it's the best.
"On a day-to-day basis, he (Mourinho) will be pushing for signs of improvement, working to progress the individual but ultimately for the benefit of the team."
Of Mata's likely role as a winger, as opposed to the playmaking position he held last season, Holland added: "It's another adaptation that is required. Juan has shown in his time here that he's more than capable of doing that. And I'm sure that will be the case this time."
