Football Insider analyses three talking points from Manchester United’s 1-1 draw against Arsenal in Saturday’s lunchtime Premier League clash at Old Trafford.

Rojo will never be a centre-back

Worry stretched on the faces of United fans when Arsenal looked to attack the defence of United, with both Phil Jones and Marcos Rojo failing to convince doubters once again with their defensive display. Argentina international Rojo looked nervous throughout the match, misplacing passes and was nowhere to be seen for Olivier Giroud’s late equaliser. Jones was slightly better, making a number of convincing interceptions and tackles throughout but was completely overawed following the introduction of Giroud. He was caught on the ground as Arsenal’s unmarked number 12 headed home.

Rashford must be handed attacking spearhead role

With the world’s football critics glued to the screen, Marcus Rashford proved why Jose Mourinho needs to give him a chance as United’s number nine. The 19-year-old was in buoyant form after finally being given a chance to start up front over the suspended Zlatan Ibrahimovich, instead of being pushed out wide. The England international’s electrifying pace caught the eye, as his constant movement bamboozled Gunners centre-backs Shkodran Mustafi and Laurent Koscielny. Such was his performance, that Rashford should be given an extended run in the side as United’s striker. Ibrahimovich has struggled to come to terms with the rigours of the Premier League, scoring just three goals in 12 games and Rashford looks to have capitalised on that.

Mata proves Mourinho wrong

Mata and Mourinho have not always seen eye to eye after the Portugese sold the attacking midfield star to United back in January 2014. Onlookers believed that Mata’s career at Old Trafford may have been over following Mourinho’s arrival. But that bad feeling is over. The Spaniard was booked for his celebration for celebrating with the fans, while Mourinho passionately punched the air with delight in his technical area as United’s number eight swept home the winner in the 68th minute. If all long-lasting memories of their fall out at Chelsea had not been extinguished, they have been now.
