Manchester United have opened talks with Juventus over a potential swap deal involving Paulo Dybala and Romelu Lukaku, sources have told ESPN FC.

United are still in discussion with Inter Milan over a deal for Lukaku but are growing frustrated with the San Siro outfit's failure to match the asking price, which has prompted negotiations with Juventus.

Talks are still at a very early stage and a deal is said to be a long way off but an agreement would see Lukaku, who wants to leave Old Trafford this summer, join Juventus with Dybala moving in the opposite direction. Inter have seen a £54 million bid for the Belgium international rejected by United, who are holding out for between £80 million and £90 million.

Sources have told ESPN FC that Dybala has reservations about joining a club who are not in the Champions League next season but is open to discussions with Ole Gunnar Solskjaer's side if a deal can be agreed.

United flew to Oslo for a friendly with Kristiansund on Monday without Lukaku, who has stayed behind at Carrington to continue his recovery from an ankle injury.

The striker has made it clear to United he would like to leave this summer and, despite Juventus' interest, Inter remains his first choice. The 26-year-old wants to link up with manager Antonio Conte, who tried to sign him during his spell in charge of Chelsea.
