Unai Emery is concerned about the welfare of his players during a busy calendar.
Villa boss Unai Emery has urged international managers to do more to help protect players from “excessive” workloads.
Emery is concerned by the amount of football played by some members of his squad during the recent three-week international break.
Captain John McGinn featured in all but three minutes of Scotland’s four Nations League fixtures.
With Villa having now entered their own hectic period of nine matches in four weeks, Emery has questioned whether his international counterparts are doing enough to ensure players aren’t placed at greater risk of injury.
The Spaniard wants more to follow the lead of Germany boss Jurgen Klopp, who selected two different squads for his team’s four matches.
Emery said: “Some coaches have been very vocal about the demands of the football calendar and the importance of protecting players from excessive workloads.
“It is a concern that deserves serious attention, particularly when players are expected to compete in several matches within a short period of time.
“Some national team managers, such as Jurgen Klopp, have even acknowledged that playing four matches during an international break is too much, and it becomes more excessive when certain players are playing virtually every minute.
“We have to think about players’ health and wellbeing.
“We try to do that at club level and I think some national team managers are setting a good example by starting to take the same approach. Hopefully, others will follow their lead.”
McGinn, capped 93 times by Scotland, has played an average of almost 60 matches for club and country over the last three seasons.
Emery, who previously branded the extended three-week break as “crazy”, said: “I do believe there should be a system for managing players’ workloads, similar to what we do at club level.
“It is important to monitor the minutes players are playing and take into account the physical load each player is carrying.”
