Casemiro was taken off during the second half of United’s 3-0 win over Leicester at Old Trafford.

A Manchester United pundit has spotted what Casemiro did after being substituted by Ruud van Nistelrooy in his side’s 3-0 win over Leicester – and it speaks volumes.

Van Nistelrooy was taking charge of his fourth and final match in interim control of United following the sacking of Erik ten Hag.

United have won three and drawn one of those four matches, with the 3-0 victory over Leicester putting them in 13th place in the Premier League table.

Van Nistelrooy will now step aside as Ruben Amorim officially takes charge as manager from today, although the Daily Mail report that the Portuguese is still waiting on a work permit and cannot yet take a training session.

That effectively means United legend Van Nistelrooy will serve as head coach for a few more days yet – although the Dutchman has said he is unsure whether he will stay on at the club under the new regime.

During his short time in charge, Van Nistelrooy paired up Manuel Ugarte and Casemiro in midfield, with some success.

He decided during the second half against Leicester to switch things up with 10 minutes to play, and took Casemiro off with the score at 2-0 and replaced him with Christian Eriksen.

MUTV pundit Danny Webber noted how, rather than be disappointed with Van Nistelrooy’s decision, the Brazilian warmly shook his hand and embraced him – appearing to be an indication of how the 48-year-old is viewed among the players.

Webber said: “It’s probably helped [that Van Nistelrooy was placed in interim charge], especially the fact that he’s worked one on one with plenty of these players.

“When Casemiro came off, Casemiro could not let go of Ruud, giving him that hug to say thank you.

“It means a lot, and says a lot about Ruud van Nistelrooy’s character that he can, in the space of 10 days, really just get that respect straight away.”

United are next in action against Ipswich Town after the international break on November 24 – with Amorim hoping that he can still have plenty of time on the training pitches before the trip to Portman Road.
