Daniel Farke is willing to upset his Norwich City players to bring success to Carrow Road.

The Canaries end their German tour on Thursday against Bundesliga opponents VfL Wolfsburg, and Farke is now busy nailing down a starting roster for the Championship opener at Birmingham.

City's head coach opted to only make changes in the final quarter of the midweek 2-1 friendly loss to FC Union Berlin as he looks to find the right league formula.

'I am not here for the Nobel Peace Prize.

'I want to bring success to this squad and I have to be smart,' he said. 'I have to decide from what I see on the training pitch and the games. Then we have to find a side competitive at Birmingham. We are nearly four weeks into pre-season.

'It is not like we go further on with trying to give all the lads the same minutes. Now it is also about the right formations for the first game.'

Farke hinted ahead of the test against the Wolves he will keep Grant Hanley, Ivo Pinto and Emi Buendia in reserve until the squad return to England, with the trio working their way back to fitness after early pre-season injury concerns.

'Jamal Lewis has only just returned to full training after a stomach bug in the last few days, but Tom Trybull is in the mix to after recovering from a swollen foot suffered in the opening tour win over SC Paderborn.

'There was a pretty hard tackle on him against Paderborn and he had swollen feet and a swollen chin. Not a big concern. He should be available for Wolfsburg,' said Farke. 'Jamal is a bit tricky. He had a problem with his stomach.

'He was on the toilet for three days and was not able to do his rehab work but should be back next week. The other three are training on the pitch and working with the balls.

'They are not back in team training.

'It is a bit difficult out here because we have these games and it is preparing each session around the next game, so it is difficult to maybe involve them. At the latest, I expect them to be fully involved when we get back to England.'

Wolfsburg should provide the stiffest test so far of Norwich's pre-season preparations.

Timm Klose's former club are looking to rebuild under coach Bruno Labaddia after retaining their German top-flight status by winning a relegation play-off last season.
