New Schalke goalkeeper Timo Hildebrand wants to restore his confidence in the reserves before stepping up to the first team.
The 32-year-old former Germany international joined the Bundesliga club last week on a free transfer after leaving Sporting.
Hildebrand had spent time on trial with Manchester City after his disappointing year with Sporting, but he joined Schalke and now admits he needs to rebuild some self-belief.
He told Reviersport newspaper: "I am not overconfident. I do not need to start first-team matches immediately.
"I have to work hard and lend myself to the manager via training."
Schalke signed Hildebrand after first-team regular Ralf Fahrmann sustained a cruciate ligament injury.
And general manager Horst Heldt has indicated the club will be prepared to support their new player's wishes.
Horst said: "We have agreed with Timo Hildebrand he first needs to pick up action with the reserves.
"He needs to get practice. Our reserves are playing a friendly against Standard Liege on Wednesday. Timo will be starting as goalkeeper then."
