Pep Guardiola says he has complete faith that John Stones has the character to recover from his Manchester City setback.
The former Everton defender was signed by Guardiola for £47.5 million on a six-year deal, making him the world's second most expensive defender, behind David Luiz.
The 22-year-old played the majority of the season for City before being dropped after the 4-2 loss to Leicester.
The club went onto defeat Watford 2-0 and Arsenal 2-1, but Guardiola says he still trusts his record signing, although he admits the England international must improve to regain his place in the side.
Guardiola said: "I know that people think if a player doesn't play it is because the coach doesn't trust him any more. That is not the truth."
He added: "It's the first time in his career he played every three days.
"He has to improve but he's open and he has a lot of personality. When you play in the big teams, the character is there. I have no doubts John has that."
City play Hull on Boxing Day before taking on Liverpool on Saturday and Burnley on Monday.
