Manchester United have expressed interest in Napoli midfielder Piotr Zielinski.

The Poland international has been a long-term target for Liverpool manager Jurgen Klopp.

Corriere del Mezzogiorno says Zielinski's entourage have been contacted by United to discuss a potential deal this summer.

Liverpool are also interested in the Napoli midfielder, who has three-years left on his current deal.

Zielinski has been a target for Klopp since he was in charge of Borussia Dortmund.
