There was a lot of hype surrounding Timothy Fosu-Mensah when he made his Manchester United debut under Louis van Gaal in 2016.The Dutch defender was just 18 years old at the time and it was hoped he would go on to establish himself as a regular at the club.Van Gaal was replaced by Jose Mourinho that summer, but the Portuguese manager was clearly impressed by Fosu-Mensah and handed him a new contract just a few months into his reign."Tim is a young player with great potential," Mourinho said after Fosu-Mensah penned a new four-year contract in October 2016. "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."Fosu-Mensah spent last season on loan at Crystal Palace and is currently spending time at Fulham.Man United fans still rate him highly and hope he can make it to the first team, but what do Fulham fans think?Unfortunately, it seems they don't have a very high opinion of him.Fosu-Mensah has played just 502 minutes in the Premier League for The Cottagers this season.Largely deployed as a right-back, Fulham have conceded 12 times while the Dutch defender has been on the pitch.His most recent performance came against Huddersfield on Monday night, and it's fair to say it was a disaster.Huddersfield hadn't scored at home since 14 April, but that streak was ended yesterday when Fosu-Mensah headed into his own net.The 20-year-old's performance did not get any better and was booked for a rash challenge after 34 minutes.He was eventually hooked off at half-time.Fulham would go on to lose 1-0, leaving them rock bottom in the Premier League.And a lot of the club's fans directed their anger at Fosu-Mensah after the game.Many have had enough of Fosu-Mensah and want to see his loan terminated.

That is worrying. If Fosu-Mensah is failing to make an impression at Fulham, what chance does he have of making it in Man United's first team?

Fortunately, at 20 years old, Fosu-Mensah still has his football career ahead of him and can still develop into the player Man United fans hoped he would be.

But, it's fair to say he hasn't quite lived up to expectations as of yet.
