The Brazilian, signed for £70m from Real Madrid in the summer, made his debut against Southampton last weekend.
Casemiro came on with 11 minutes remaining and helped United see out the victory.
He was named among the substitutes once again for the match against Leicester at the King Power Stadium.
He was given a longer chance to impress by Erik ten Hag as he replaced Anthony Elanga in the 59th minute.
And the 31-year-old was solid during his time on the pitch.
Casemiro was a commanding presence in the middle of midfield as he shielded the defense effectively and also displayed some impressive passing.
He played a key role as United held on to their lead and clinched all three points.
His highlights from the match have now been posted by YouTube user Ahdaf Kooora. View them below…

Casemiro was impressive against Leicester and there’s plenty more to come.
The Brazilian is not yet accused of United’s style of play, as noted by Ten Hag in his post-match interview.
“He has to get used to a different league. He has achieved everything possible and now has to adapt to his new team-mates,” Ten Hag said of Casemiro, per BBC’s Shamoon Hafez.
Once Casemiro is up to speed, he has the ability to dominate the Premier League.
He took to Twitter after the match to post about his side’s ‘great win’.

Casemiro will look to make his full debut for the club when they take on Arsenal in a mouthwatering clash at Old Trafford on Sunday afternoon.
The Gunners have won all five of their games to start the campaign and are flying high at the top of the table.
But United are high on confidence themselves and will fancy themselves to come away with a victory.
Arsenal will be hoping that Casemiro is not named in the starting lineup, that’s for sure.
