West Bromwich Albion boss Steve Clarke is unhappy with this week's international friendlies.
Clarke has called on the authorities to standardise the schedule.
"The international breaks have not been good for us because we have lost both games when we've come back," Clarke told the WBA website.
"There is something in motion to change the international schedule, which I think comes in next season.
"The sooner they set it out and standardise it so every country in the world is following the same pattern, the better.
"But we know it's there and we have to deal with it, and other clubs have the same problems."
