Sunderland boss Roy Keane admits he expects to buy big again in January.

Keane has spent almost £50million since taking over last season but will be seeking further financial support from the club's Irish backers.

Sunderland are 16th in the Premier League and are seeking their first away win at West Ham tomorrow.

But Keane is already looking ahead to the transfer window and said: "It would be great to get to January and look to add one or two players, like the big boys. Unfortunately, having just got into the Premier League we need more than one or two."
