There seems to be a lot of arrogance on this thread. We play the better brand of football and Utd have had an indifferent start to the season but they are an effective team and you dont go to Jve and win without being a well organised and strong team (the got a bit of luck but every team gets that at points).
Make no mistake they can hurt us and we need to be at the top of our game. The pace of Martial is a danger and as much as we deride Pogba, some of it deservedly (who will play make no mistake about it), he has the attributes to hurt us with late runs into the box and being decent in the air as well. Even int he also few games we have won handsomely we have given up chances to the likes of Burnely, Southampton and Shaktar that the likes of Martial and pogba as well as Sanchez will take advantage of.
I think its more dangerous for us if Lukaku doesn't play as well..they are more mobile without him and will try to get in behind us more.
Of course we can hurt them but PEG will see his team up to play very defensively and hope to get us with set plays and breakaways...any free kicks around the box or around the wide areas we need to be very cautious of.
