Agree with your first sentence but United aren't a defensive-minded team (which is what you are alluding to when comparing them to Leicester and Mourinho's Chelsea). Half way through the season and United are scoring at 1.5 gpg (2 more than Bournemouth and 3 more than Everton and WBA, 1 more than Palace, over 20 games) and you have only conceded 4 goals less (so 0.95 pg) than Liverpool (1.15pg) whose defence no one on RedCafe rates in the slightest. The reality being both are actually very good defensive records.
No matter which way you cut it that goal-scoring record isn't good enough for a Top 6 team and yet everyone here seems to think United have some shit-hot attack. The reality is you have one real goal-scorer, Ibra, and considering your next two are Mata and Pogba with 4 each you must be praying Ibra stays fit and can last the season. Red Blinkers or what (I know this is going to come back to bite me on Sunday)
