Manchester - Matteo Darmian believes the Manchester United players need to step up their game when they take on Arsenal in a crunch Premier League tie on Saturday. The Red Devils have experienced an underwhelming start to their season under new manager Jose Mourinho, and currently sit in sixth place on the league table, eight points off the top. Their inconsistent performances have put pressure on Mourinho, but Darmian insists the players need to play to their potential and show character in tough situations. “The players, we have a responsibility," Darmian told the Daily Mail. “We have to do more out there on the pitch. We have to play with our hearts. “I am feeling confident. After this break, we now have to be focused on the next game. “It’s a big game against one of our big rivals for the title. We have to prepare in just two days of training but we need three points and we have to be focused to get that.”Darmian also admitted that he was mystified at being overlooked by Jose Mourinho earlier in the season.The 26-year-old was only handed his first outing of 2016/17 against Feyenoord as United opened their Europa League campaign with a 1-0 defeat at De Kuip.United next welcome an Arsenal side to Old Trafford who sit second on the table with Mourinho's men looking to put pressure on the front runners for the league title.Kickoff is at 1430.
