Arsenal, Tottenham Hotspur and Manchester United are reportedly interested in Everton midfielder James McCarthy.
The 24-year-old signed a five-year deal when he moved to Goodison Park from Wigan Athletic for £13m in 2013.
However, it is thought that while several key players have since opened discussions over new terms with the Toffees, McCarthy is yet to have been approached.
The Republic of Ireland international has established himself as a consistent performer in the Premier League since joining Everton.
Arsenal, Spurs and United are all said to be keen to bolster their squads with a proven midfielder.
Arsenal and Spurs have been monitoring McCarthy for several months, while United have identified him as an alternative to Roma's Kevin Strootman, according to the Daily Mail.
McCarthy has made 24 appearances in all competitions for Everton this term.
