Casemiro has made an instant - and significant - impact on the pitch since since moving to Old Trafford in the summer.
But fresh information has now come to light highlighting how the Brazilian midfielder has also driven standards off the pitch during his fledgling Manchester United career.
Since his £60million transfer from Real Madrid, the 30-year-old has been influential in a team that has been revitalised by Erik ten Hag.
After being slowly integrated into the team, including a seven week wait for his first Manchester United, Casemiro has pulled the strings for United, who have won 11 of their last 12 games. The multi-time Champions League winner has inspired his new team-mates on the pitch; and it turns out he has also been leading by example at the club's Carrington training base and beyond.
A new report from The Telegraph has detailed how Casemiro has helped drive standards since arriving at the club. It is noted that he is one of the first people to arrive for training and one of the last to leave and that he, along with Bruno Fernandes and David de Gea, often arrives early to have breakfast with team-mates at the club.
Casemiro's approach has earned him plenty of plaudits from within United. His professionalism has been lauded and it has also been claimed that Casemiro has a 'quiet authority' which has rubbed off on a group that lacked discipline and direction during a tumultuous campaign last year.
As well as undertaking English lessons at the club, Casemiro has also been having extra lessons away from the club's training base in a bid to accelerate the process. He believes that improving his understanding of the language as his 'greatest urgency'.

The report goes on to outline that sources close to Casemiro claim he has told them that he has "never been this comfortable or happy in his career" - despite the fact he became almost synonymous with success during a trophy-laden spell at Real Madrid which spanned just shy of a decade.
Nobody will be happier with the impact Casemiro has made than Ten Hag, who admitted last month he was delighted that Real Madrid decided to part ways with the "magnificent" midfielder in the summer.
"I am happy they did!" Ten Hag said in December when he quizzed about Real's decision to sell Casemiro. "But you see also at the World Cup he is a magnificent player. My analysis before the season was we needed that 6 position and he is fulfilling that position.
"In pre-season, we had a lot of discussions but you need the right player and we definitely have the right player. I am really happy for Manchester United, for this team to have him because he is really raising the limits for Manchester United."
