He is pleased that the international calendar has rescheduled matches for Tuesday to give clubs a vital extra 24 hours of preparation for domestic weekend commitments.
"You've just got to accept it," he told MUTV. "There's nothing you can do about it.
"Over the last year, we had Paul [Scholes], Gary [Neville], Ryan [Giggs] and Edwin [van der Sar] who had retired from internationals so we had the benefit of having those players for weekends. Now those players, bar Giggsy, are away from us so most of the players are going to internationals.
"We have to keep our fingers crossed that they come back healthy. Sometimes we're lucky, sometimes we're not. It's not in our hands.
"The only benefit is the internationals are now Tuesday fixtures and that gives us an extra day to prepare for weekend games."
