Maguire and Casemiro are out of contract at the end of the season but have played influential roles in the club’s improvement under Michael Carrick.

Carrick oversaw an impressive victory over Aston Villa on Sunday as United remained in the driving seat for a Champions League spot.

Casemiro, Matheus Cunha and substitute Benjamin Sesko were on target at Old Trafford.

Co-owner Ratcliffe told Sky News earlier this month that the United Kingdom had been “colonised by immigrants”.

The 33-year-old Brazilian midfielder is out of contract in July and his departure was announced on Thursday.

The 24-year-old defender has been injured since August.

Casemiro, on his return from injury, was replaced at half-time of the 3-0 defeat and United have now confirmed he will miss a key run of fixtures.
