Inter Milan midfielder Mateo Kovacic has grown increasingly frustrated with a lack of playing time at the San Siro this season, which according to Sport Mediaset has alerted Arsenal, Manchester United and Borussia Dortmund to the possibility of a €15m summer switch.
Kovacic was signed by Inter last January for €11m and immediately got a chance to shine in Serie A, with previous Nerazzurri coach Andrea Stramaccioni happy to let the teenager start in central midfield.
Current Inter boss Walter Mazzarri has been more sparing in his use of the Croatian playmaker though, allowing the 19-year-old to complete 90 minutes just four times in all competitions this season.
A total of 24 Serie A appearances looks healthy on paper but Kovacic is not happy, with Sport Mediaset revealing that the starlet is ready to ask for a move if he is unable to force a change in his current situation in time for next season.
That stance has a clutch of European clubs watching the situation closely, alerted to the possibility of signing a player who made his Champions League debut at just 17 with Dinamo Zagreb.
Inter are building for the future under new, wealthy owners, but will reportedly consider Kovacic's future if they receive of a bid of at least €15m and the youngster goes public with his discontent.
Arsenal, United and Dortmund are all poised to take advantage of the situation and have had Kovacic watched this season, but will wait until Inter show their hand this summer before making a decision on any official bid.
