Manchester City boss Sven Goran Eriksson admits he hasn't a clue how Steve Bruce will set out Wigan Athletic this weekend.

In fact, on Saturday, against Wigan, Eriksson will be opposite Steve Bruce for the second time in six weeks. The Blues then play Spurs twice and Bolton.

He accepts most of the old scouting reports will have to be scrapped as the new men put their own imprint on things.

"In Spurs case with Juande Ramos, we have had time to see how they are playing and I watched them on television against West Ham, but when it comes to Wigan I don't have a clue how they will line up under Steve Bruce," said Eriksson.

"It is his first game and I don't know what ideas he has at this moment. I don't know if that is an advantage to him or not, because he has already managed a Birmingham side against us who did very well. We will have to wait and see."
