Donny van de Beek's agent has reportedly sent a threat to Manchester United after revealing they blocked the midfielder from departing on loan in the summer transfer window.

The Dutch international arrived at Old Trafford from Ajax at the beginning of last season, and featured in just 19 Premier League games over the course of the campaign.

Van de Beek then missed out on Euro 2020 after suffering an injury in the lead up to the summer's tournament, and he is yet to play a minute of Premier League football this season.

Amid links away from the Red Devils throughout the summer, the Dutch midfielder and his agent Guido Albers were said to be keen on a loan move to Everton on deadline day, only for manager Ole Gunnar Solskjaer to block van de Beek's exit.

"We had conversations with Solskjær and the board," Albers said, according to The Mirror. "We took the initiative to find a club and our search ended up at Everton. We opened talks with Marcel Brands and Farhad Moshiri.

"On Monday night [before deadline day] we received a call from Solskjaer and the club who told us that a transfer was out of the question and that he had to report himself to training the next morning."

While the Dutch international remains at Old Trafford, Albers has reportedly made it clear that his client wants regular minutes in the English top flight, and the midfielder is said to have cleared the air with Solskjaer ahead of the return to league action.
