Mark Hughes has urged international coaches to put more thought into picking players following an injury to Martin Petrov.
Manchester City winger Petrov is facing a lengthy spell on the sidelines after suffering knee ligament damage in a World Cup qualifier for Bulgaria.
Petrov was hurt during the first half of Wednesday's 0-0 draw with Georgia, having played almost a full game against Italy on the previous Saturday.
Prior to his international call-up, Petrov had made just two brief substitute appearances for City after over a month out with hamstring and knee trouble.
With the exciting wide man now set for a spell out, City manager Hughes believes more consideration should be given to a player's fitness by international bosses.
"It is a difficult job being an international manager as they have only a certain number of games to make an impression and sometimes even to keep their jobs," said the former Wales coach.
"So they have to have as many key personnel at their disposal as possible. But on occasions they need to be a bit more thoughtful, regarding the player and his future.
"If players are coming back from injury and they have only had maybe 20 minutes here and 20 minutes there in certain games, they would perhaps benefit from missing the first game and be fit and well for the next one.
"It is always difficult for managers at any level if they have players on international duty. You are not in control of their day-to-day training."
