On that note, let's take a look at5 Manchester United players who underperformed against Watford#5 Nemanja MaticLeicester City v Manchester United - Premier LeagueFollowing poor performances from Fred and Scott McTominay, Solskjaer turned to veteran defensive midfielder Nemanja Matic against Watford. The Serbian has undoubtedly been one of the best in business for the majority of the last decade. He was unfortunately unable to deliver the goods against Watford.Matic was unable to produce the performance needed to stop Watford's midfielder from utilizing the flaws in midfield. The 33-year-old was dominated by Sarr and Cleverly for the majority of the game as Watford took advantage of gaping holes in United's defense.#4 Bruno FernandesManchester United v Atalanta: Group F - UEFA Champions LeagueBruno Fernandes has proven himself to be one of the best midfielders in the Premier League. The Portuguese often remains the difference maker for Manchester United but he was completely indecisive against Watford.Bruno was well marked throughout the match and was unable to make any impact whatsoever. The midfielder's passing lane was cut-off by the opposition and he was unable to be of any help to Solskjaer's men.His mistake also gave away a penalty early in the game but Sarr failed to convert it for Watford.Fabrizio Romano@FabrizioRomanoOle Gunnar Solskjær apologies to Man United fans.
