Everton's out-of-contract Steve Watson is being chased by four clubs.
Blackburn, Wigan, Leeds and Sunderland are all interested in signing the 31-year-old, who is expected to leave Everton on a free transfer.
Watson was dogged by injury problems last season and made only occasional appearances as Everton finished fourth and qualified for the Champions League.
Watson, who joined Everton from Aston Villa in July 2000, is unlikely to sign a new deal at Goodison Park.
