The toughest period for any team vying for the top prize in English football are the months of February and March.
This period is when teams struggle to retain their form, egos explode inside the dressing rooms, and titles are seemingly lost and won by teams that falter and those who remain resilient, respectively.
Unfortunately, Manchester United have suffered a great setback as one of their talismen in Antonio Valencia got injured during the Europa League game against Ajax Amsterdam.
Valencia was on the field only for a short period of time when he pulled a hamstring and was substituted soon thereafter. News is that Valencia will be sidelined for at least four weeks.
What does this mean for Manchester United? Is the loss of Antonio Valencia as big as a loss, as say losing Wayne Rooney?
In my opinion, the answer is a resounding yes.
The injury couldn’t have come at a more sign
