3 Things We Learned From Manchester United and Arsenal's Entertaining Draw

Manchester United and Arsenal were forced to settle for a point each after an entertaining match ended 2-2 at Old Trafford. A howler from David de Gea gave Arsenal the lead, but United hit back not long after through Anthony Martial. 

The second half lacked in defensive solidity, but was just as entertaining, a bizarre two minutes saw Arsenal take a freak lead before United equalised straight from kick off.

1. Defending Is an Alien Concept to These Sides

We've found out pretty quickly this season that any game involving Manchester United will probably include goals, but this was a step too far even for them. At one point during the second half both teams completely gave up on tracking back and the game started to look like a playground match where everyone was chasing the ball.

Both United and Arsenal will need to address their defensive woes, that may come in the form of a change in system.

2. Eric Bailly Must Start for Manchester United

United's defence has been their main problem so far this season, and whilst they still conceded two goals against Arsenal, they looked a lot better with Bailly at the back.

His speed was on show in a foot race with the rapid Pierre-Emerick Aubameyang which he won, and while he still leaves a lot to be desired on the ball, he's clearly United's best option in that position.

3. Arsenal's Luck Will Run Out

They've been outperforming their attacking numbers since the start of the season, and once again Arsenal should be counting their lucky stars that they came away with a point at Old Trafford.

This isn't to say the Gunners played badly - some of their attacking play was excellent. But the two goals they scored were flukes, David de Gea should never palm the first into his own goal, and the second was even luckier.

Arsenal are a good side, but they're due a downturn in results, this sort of thing won't happen all season.
