Casemiro scored his 9th goal of the season on Monday, fueling Manchester United's push for a Champions League spot. The 34-year-old midfielder has been instrumental in United's drastic improvement this season.

What's behind Casemiro's resurgence?

Casemiro's unexpected turnaround has been propelled by his rediscovered energy and tenacity, which made him one of the world's most dominant defensive midfielders at Real Madrid.

The experienced midfielder has benefitted from regularly playing one game a week, and the appointment of Michael Carrick has breathed a new lease of life into his career.

He has been trusted to anchor the midfield, and has been surrounded by players with pace and energy, allowing him to do his job more effectively.

How has Casemiro contributed to United's improvement?

Casemiro's goals have been a significant factor in United's improvement, with eight of his nine goals coming from set pieces. He has become the most dangerous set-piece threat in the Premier League.

The Brazilian midfielder has also benefitted from the attention United have given to set pieces, and the excellent delivery from players like Bruno Fernandes.

What does this mean for Manchester United?

Casemiro's performances have been pivotal in securing United's all but certain return to Champions League football, and the financial rewards that come with it. He has paid back some of the £70m transfer fee and £375k a week wages paid for and to him.

The midfielder has become a fan favourite, with his name being chanted repeatedly towards the end of the victory over Brentford. His resurgence has given Man Utd a problem they did not think they would have, as they look to secure a Champions League spot.

On Monday, Casemiro scored his 9th goal of the season in the 2-1 win over Brentford, a result that has propelled United to the verge of securing a return to Champions League football. The experienced midfielder has confirmed that he will leave United at the end of the season, but his current form has been a significant boost to the team.
