Nearly everyone, including the United faithful, had their money on an Arsenal win but a late error by Sead Kolasinac allowed the home side to level the score for the second time as the game ended 2-2 at the full-time whistle.
"There have been more rumours of Jose Mourinho leaving Manchester United".
After his poor performance in the 2-2 draw with Southampton last Saturday, Pogba was dropped by Mourinho for Arsenal's visit to Old Trafford and was only brought on with 15 minutes remaining. He has also been an unused replacement in five of the past seven games.
Mourinho says he is reluctant to play the midfielder until he gets used to the Premier League and becomes better at positional discipline because the United defence needs protection.
"[We are taking it] step by step", Mourinho said when asked about Fred in Friday's media conference.
United, in eighth place in the Premier League, have already conceded 25 goals this season - compared with Liverpool's six - and have a goal difference of minus one.
"You have other players at other clubs that needed time and some of them played even less than what Fred is playing".
"We're in it as a team".
Arsenal are a good side, but they're due a downturn in results, this sort of thing won't happen all season. "They are led by one of the two most important managers in the history of the Premier League, so they have the potential to come here tomorrow and to give us a very hard match".
