• Rise of Manchester United midfielder Kobbie Mainoo highlights Chelsea's missed opportunity
• Mainoo caught the eye with his England debut, a result of his impressive performances for Man Utd
• Thomas Tuchel's mismanagement led to the departure of talented player Billy Gilmour

The rise of Manchester United midfielder Kobbie Mainoo has been unavoidable in recent weeks, yet Chelsea should have had their own version of the teenager, only to squander their gem thanks to the mismanagement of Thomas Tuchel.

Mainoo caught the eye as he made his England debut in a 22 draw against Belgium earlier this week, but his performances with Man Utd had made his selection inevitable.

He is just the type of player that Chelsea are searching for in their pursuit of a team to have both immediate quality but also longterm potential.
