Jose Mourinho has a reputation in football as a manager that isn't keen on giving youth a chance.
While he has certainly spent some money in his time, Mourinho has also used his expertise to improve players from club academies.
At United, the Portuguese has been key in Jesse Lingard's rise to an established Premier League star.
He's now a key man in the England setup as well, but what about the other Englishmen Mourinho has tried to aid in his time in the Premier League?
Well, here's the eight English players Mourinho gave official debuts to during his two spells with Chelsea.
Made just one appearance for Chelsea, coming on to replace Joe Cole in a 3-1 win against Manchester United at Old Trafford.
But it was downhill from there, with Grant playing for nine different Football League clubs in just 12 years. He's now at Shrewsbury Town.
Just like Grant, Smith made just one appearance for Chelsea, coming on as a sub in a 1-0 win against Newcastle in the Premier League.
After several loans, the winger joined Leyton Orient in 2009, making 144 appearances. Smith is now with Crawley Town in League Two.
The central midfielder made two substitute appearances in the FA Cup during Mourinho's first year in charge of Chelsea.
Was finally released by the Blues in 2011, playing for Yeovil, Doncaster Rovers and Harrogate. Woods joined Hartlepool in 2014 where he's become an important player.
Probably the only familiar debutant from Mourinho's first Chelsea spell. Was handed his chance as an 18-year-old in 2007, but actually retired from the game at 21 due to a knee injury.
Hutchinson then made a comeback in 2011, having loans at Nottingham Forest and Vitesse Arnhem, before joining Sheffield Wednesday in 2014
Big things are still expected of the 23-year-old attacking midfielder, who excelled for Vitesse on loan between 2015 and 2017.
Was handed his Chelsea debut against Derby in the FA Cup back in 2014 - playing just three minutes - and he's currently on loan at Leeds United.
The highly-rated striker only played for Chelsea once, replacing Oscar in a 6-0 thrashing of Maribor in the Champions League back in 2014.
Was loaned to Vitesse for the 2015/16 season, before joining Liverpool in 2017.
The one player still at the club. Loftus-Cheek is currently trying to usurp Mateo Kovacic in Maurizio Sarri's starting XI.
Mourinho handed him his debut in the Champions League against Sporting Lisbon, replacing Cesc Fabregas.
His solitary appearance for Chelsea came when he replaced Eden Hazard in the 89th minute against Cardiff in 2014.
Was sent out on loan to Rotherham, Brentford and Swindon, before making a permanent move to Reading in 2016.
