When the Premier League season kicks off in August, the Red Devils may not have the strongest squad on paper, but as a team, there is no stronger dynamic.
Even without performing wingers and only one consistent central midfielder, United were virtually unstoppable for much of the campaign.
Chelsea, City, Arsenal—these clubs could not overcome their deficiencies; Sir Alex's side thrived.
Moyes seems to have pinpointed these weaknesses and will likely bring in a box-to-box midfielder to go with the already signed Wilfried Zaha.
Beyond quality, United also have the strongest squad mentally.
When the going gets tough down the stretch, there is no other group of players you would back to pull through and deliver.
