Although Man United haven't really come remotely close to producing the Class of '92 since, a few eye-catching youngsters still make their way to the Old Trafford turf from time-to-time.Timothy Fosu-Mensah is one such player and the 19-year-old began to make waves under Louis Van Gaal at the back end of his final season in charge at the club.The former Ajax man has made 21 appearances for the Red Devils since his debut - 12 in the Premier League - and now finds himself on loan in London with Crystal Palace.However, his time at Selhurst Park has been very different to what he is used to at the Theatre of Dreams.The Eagles may have beaten champions Chelsea 2-1 in their last outing, but they are still rock bottom in the Premier League having failed to score or get a point in their other seven games this term.It's been a steep learning curve for Fosu-Mensah, who made a five-minute cameo in the Chelsea win, and it seems as though he may not be used to criticism.Several fans on Twitter believe they have uncovered a secondary account the new Dutch international uses to defend his performances on Twitter.As you can see from the tweets and screenshots below, it's pretty tragic.

Fosu-Mensah even goes as far as to reply to the account when searching for someone to make a compilation of him.

While Fosu-Mensah is yet to be fully exposed like NBA superstar Kevin Durant was, the evidence is pretty glaring.

Speaking last month, Fosu-Mensah explained why his loan deal at Selhurst Park is important and how he hopes to build upon his Dutch debut.

“I am using the opportunity to get game time in the Premier League and gain more experience, I am keeping in contact with Manchester United and I know that their coaching staff are monitoring my progress so I am just hoping all goes well for me.

“It was tremendous to get the opportunity to make my debut last month for the Netherlands and I am just looking to build my international career on from there and hopefully be a regular in the team. There is a lot of competition for places but we all know that is what it is like in this game and I am ready for the challenge.”
