Sunderland boss Roy Keane has revealed he was offered the chance to sign Johann Vogel.

The Switzerland midfielder is available on a free transfer after leaving Real Betis at the end of last month.

Vogel was linked with a switch to Sunderland, but Keane has not followed up an opportunity to sign the experienced anchor man.

"He was a player who was brought to our attention, but if I showed you a list of players who were brought to our attention in any given week you'd be surprised how long the list would be," Keane told the Sunderland Echo.

"We are still looking at strengthening the side, but stories of players turning us down left, right and centre simply aren't the case."
