Stoke boss Mark Hughes is the latest club manager to bemoan the cost of the international week as he accused Wales of "compromising" the fitness of Joe Allen.
The midfielder returned from duty with a hamstring injury, picking up the injury after scoring in the 2-2 draw in Austria.
He sat out the following game against Georgia in Cardiff, but Hughes believes Allen did too much with Chris Coleman's men - Worold Cup qualification Group D rivals to the Republic of Ireland - and as a result is a doubt for this week's Premier League clash with Sunderland.
Hughes told Stoke's official website: "We're still checking on Joe, he hasn't trained with the group yet.
"We've just got to be a little bit careful with him; unfortunately he probably did a little bit too much with the Welsh squad.
We're hopeful that he's going to be okay
"We would have given him an extra day's rest but he trained with [them] and that's probably compromised him a little bit so they have to be a little bit careful in that regard.
"We're hopeful that he's going to be okay and we'll have to check on him tomorrow."
Hughes' criticism comes after Ronald Koeman accused Ireland manager Martin O'Neill of "overloading" James McCarthy after the Everton midfielder played all but nine minutes of last week's victories over Georgia and Moldova.
"James McCarthy is a little more difficult, because after five or six weeks out of football after his surgery, he played the full game after three group sessions with Ireland," Koeman said.
"He played the second game, and he's been massively overloaded. We have to make a decision tomorrow if he's really fit to be part of the team."
