A lot of the positives and negatives are similar for me
Positives:
Martinez subs, after going 2-1 down were superb to pull us back and take the lead
Headers up front
Lukaku, 2 goals and some good play
A lot of players that were playing poorly recently suddenly found the drive, pace and passing ability they have been lacking, Mirallas, Pienaar, Barkley were superb
3 goals for
Couple of good counter attacks
The pace in our team for the above
Mirallas smashed Suarez and stayed on
Good to see us play a full game at tempo, instead of just one half and I think we look good for the coming games.
Negatives
Martinez sub, 10 minutes to go and displayed what posters have been ranting about Moyes for doing for years, and bought on a defender to shore up a 1 goal lead, subsequently handing momentum to the opposition and ultimately costing us 2 points.
Headers at the back
Lukaku, a lot of poor first touches again, poor decisions, 1 unbelievably bad pass when 4 on 2 on the counter
3 goals against
Diving has been creeping into our game regularly this season and I'll be honest I am not a fan at all. Were not to the level of the bigger teams or Liverpool but its enough to get a bit cringey.
Mirallas smashed Suarez and stayed on, but the negative lies in Mirallas not being heavy enough to of done sufficient damage.
