Timothy Fosu-Mensah has endeared himself to Manchester United fans ever since making his professional debut against Arsenal in February.
Introduced in the 55th minute to replace Marcos Rojo, the 18-year-old impressed and helped see out an impressive 3-2 victory, where fellow youngster Marcus Rashford scored a memorable brace.
A string of fine performances in the first team soon followed under then-manager Louis van Gaal and he has since been rewarded with a new four-year deal by current boss Jose Mourinho.

On signing a contract extension earlier this week, he told MUTV: "I feel very happy. It (the contract) shows that the club has a lot of confidence in me.
"I just want to pay them back with my performances on the pitch. I hope this is the first of many. I'll keep trying to develop myself."

Fosu-Mensah's most recent appearance came during Thursday night's 4-1 win over Fenerbahce, where he replaced Paul Pogba with 15 minutes remaining.
It was but a cameo for the young Dutchman but he still took to social media in the aftermath to celebrate the victory (see below).
However, while the post looks completely innocent, he sneakily - and brilliantly - trolled teammate Ander Herrera, who wasn't included in Mourinho's squad. Take a closer look.
The fourth official holding up the board looks exactly like Herrera - he really is a spitting image from the side! Minus the shaven head.
Fosu-Mensah might have even more reason to troll his Spanish teammate in the future should he eventually nail down a starting role in central midfield, where he played and impressed against Fenerbahce.
"I've not played there for a long time," he admitted. "I've played there a lot for the Under-18s and Under-21s and it was a little bit different but as soon as I was on the pitch it felt good."
Mourinho is certainly a big fan of the Netherlands Under-21 star and recently promised him increased game time under his reign.
"Tim is a young player with great potential," the Portuguese said of Fosu-Mensah's new deal. "I am pleased that he has signed a new contract and I am delighted at the progress he has made so far.
"It is clear to see that he is learning every day in training and there will be plenty of opportunities for him as the season continues."
