Everton boss Roberto Martinez is hoping to wrap up a deal to bring Wigan midfielder James McCarthy to Goodison Park - but fears late interest from Tottenham.
According to the Daily Star, McCarthy's is Martinez's main transfer target and is looking to bring him across from former club Wigan.
But the new Toffees boss fears being out-bid by Spurs, should the north London side follow up their interest with a bid.
Club chairman Daniel Levy is believed to have already notified Wigan as to his interest in the player, but has yet to come close to matching the club's £20m asking price for the midfielder.
The central midfielder was reportedly the subject of a £13m 'final' offer from the Toffees earlier this week.
But Everton fear interest from White Hart Lane will complicate matters - with Wigan likely to hold out for a higher fee.
The Scotland international made 115 Premier League appearances for the Latics before they were relegated under Martinez last season.
Wigan chairman Dave Whelan is determined to hold on to his best players to help new boss Owen Coyle in his bid for a quick return to the Premier League.
But with interest from Spurs and Everton, and Liverpool, Fulham and Manchester City also tracking developments, the Championship club face a tough task to keep him at the DW Stadium.
