"Most clubs, not just United, are finding it difficult to keep the continuity going when you lose your players for two weeks at a time," said Sir Alex.
"It is important for the national teams, so you have to support it. But the advantage is that there is a clear run after November to the Championships in the summer.
"There is a stupid friendly week in March. But I assume it will be limited teams because you are talking about a really important time of the season for league clubs. Once this next international break is out of the road in November, there is a run to the end of the season. It will help with consistency."
