Newcastle United have slapped a £50m price tag on their 21-year-old midfielder Sean Longstaff as they look to ward off interest from Manchester United .
United boss Ole Gunnar Solskjaer has already signed winger Daniel James from Swansea and right-back Aaron Wan-Bissaka from Crystal Palace this summer, and is hopeful of making Longstaff his third new addition.
United are looking to take advantage of the current uncertainty at Newcastle , who have lost manager Rafa Benitez and forward Ayoze Perez over the last few weeks.
However, Newcastle are determined to keep hold of Longstaff, who was born in the city and only made his first senior appearance for the club in December.
According to Sky Sports News they will not listen to offers of under £50m for the player, and they have told United that he is not for sale.
Longstaff made 13 appearances in all competitions last season before suffering a knee ligament injury in March, and was ruled out for the rest of the season.
Solskjaer was thought to be impressed with his performances, however, and has urged the board at United to put in an offer.
He is keen to add young British talent to his squad, and is also pursuing Leicester's Harry Maguire.
He hopes to have at least one more fresh face in his team before they jet off to Asia on their pre-season tour later this month.
Losing Longstaff would be yet another blow to Newcastle in a summer of complete turmoil at the club.
They have yet to make any signings, are managerless and have lost one of their most important players, while a takeover bid from the Bin Zayed group appears to have stalled.
Newcastle supports are desperate for owner Mike Ashley to leave the club, and have organised a series of protests against the Sports Direct chief executive.
