Mason Mount participates in his first practice after completing his transfer to Manchester United.

The international English player committed to Red Devils for an estimated 65 million pounds in a long-term contract. 

Mason Mount, 24, spent 18 years at Stamford Bridge, where he began his football schooling, before leaving for Chelsea. 

Cristiano Ronaldo's former team, the club Manchester United, has given Mount the No. 7 jersey. 

Mason Mount was seen on Friday at the Carrington training facility as they got ready for the preseason. 

The former Chelsea star practiced some shooting and ball-handling tactics. 

Mason Mount posed with Lisandro Martinez in another photo, where he seems eager to get to know his new teammates. 

Martinez recently chopped his hair blonde and returned to training. Due to an injury, the Argentine missed the season's last three games.
