Former Manchester United striker Dwight Yorke says Marouane Fellaini must prove he is good enough to play for the club. The midfielder has been criticised for a number of his recent performances, with his substitution during last weekends FA Cup match against West Ham being cheered by sections of the Old Trafford fans.He then courted further controversy during Thursdays Europa League 1-1 draw with Liverpool when appearing to elbow Roberto Firmino, resulting in a only yellow card from the referee. Ahead of Sundays Manchester derby Yorke, who played almost 100 times for United between 1998 and 2002, is challenging Fellaini to repay the faith which prompted the club to pay over £27m for his services in September 2013. It hasnt quite happened. The critics are still out, theres still uncertainty on whether he passes the test of being a Manchester United player. Dwight Yorke Speaking to Sky Sports News HQ, Yorke said: He certainly came with a big price tag. He was outstanding at Everton, and since he has come to Manchester United he has struggled and hasnt lived up to expectation.We know he is a very good player, but one thing when you come to United is you have to go from being a good player and go on further - you need to bring something totally different to the team.We expected that from Fellaini, but it hasnt quite happened. The critics are still out, theres still uncertainty on whether he passes the test of being a Manchester United player. Fellaini appeared to elbow Liverpools Roberto Frimino during Thursdays Europa League clash Yorke, who won three Premier League titles during his time at the club, believes Sundays match gives his old club the perfect opportunity to get their disappointing season back on track, following their European elimination.The players will be down in the dumps in a big way. Itll be back to the drawing board, and the players need to pick themselves up, added Yorke.The players dont need any introduction to the game - they need to finish on some sort of credibility this season and this is a perfect game to lift the spirit back in the Manchester United camp.Yorke also believes assistant manager Ryan Giggs should be handed the reins at Old Trafford should manager Louis van Gaal leave the club.It hasnt quite happened for Louis van Gaal, hell be bitterly disappointed in where Manchester United are in the league and in Europe, and whether that continues next season, only time will tell, he added.I believe Ryan Giggs should be the next manager of Manchester United after Van Gaals contract ends. He has a little bit of experience under David Moyes, he has played under the best manager to manage in the Premier League, Sir Alex Ferguson, and hes been at the club nearly 30 years.When you look at the likes of Zinedine Zidane and Luis Enrique, those guys have not had a great deal of experience - they were in a similar position as Giggs.
