Wigan manager Roberto Martinez has called for a change to the international break format ahead of Saturday's Barclays Premier League clash with Manchester United at Old Trafford.
The Latics boss is faced with a difficult couple of days ahead of one of the toughest fixtures of the season and only has a short space of time to assess his squad after 2014 World Cup qualification duty.
"I don't like the international break, I've said it many, many times," Martinez said.
He added: "This is another example. We've got 48 hours to go to one of the biggest games of our league competition and we don't even know what kind of squad we can count on. That's for ourselves, that's for Manchester United.
"As a whole, I don't think that's a healthy position for any team to be in when trying to put on a good display for the fans in what we consider to be the best league in the world."
Defender Antolin Alcaraz suffered a leg injury during Paraguay's 2-0 defeat by Venezuela and was set to only arrive back at the club on Thursday afternoon - less than 48 hours ahead of kick-off.
With another international break due next month, Martinez knows he has to be prepared for further disruption to his league campaign, but the Spaniard believes the format needs to be reassessed as it is to the detriment of the players.
"It's something that you need to adapt to but it doesn't make it right," Martinez said.
"It's trying to change a bad situation for the players into a positive one. I don't think that's right and it's unfair on the players. The answer should be playing the games with a longer recovery time before you play your next game. There are ways."
