Manchester United and Liverpool have joined Barcelona in the race to sign Atletico Madrid midfielder Koke, according to the Daily Mirror.
The 21-year-old has been in fine form for Atletico Madrid this season, featuring in all 13 of his side's La Liga games this campaign.
Koke's performances - in La Liga and the Champions League - have led to the
former Under-21 star receiving a senior call-up to Vicente del Bosque's Spain squad.
His impressive displays have also alerted the attention of a host of European clubs - with Barcelona thought to have been leading the chase to sign the Spain international.
However Premier League duo Manchester United and Liverpool are also said to be keeping a close eye on £17million-rated Koke.
Red Devils boss David Moyes, who was close to signing Koke's former Under-21 teammate Ander Herrera in the summer, is particularly keen on adding a central midfielder to his ranks in January.
