It's not a meaningless game though, it's a World Cup Qualifier, against Brazil.
The issue I have is, if he's missed an entire month, which includes 7 games for City, then as far as I'm concerned his nation shouldn't be calling him up. In scenarios like that one, where a player has clearly been out injured for a period of time prior to the international break, and hasn't managed to get himself fit enough to play for his actual employer, then it should be common practice that the player isn't deemed to be available for his national side. Not yet able to play for your club, then not yet able to play for your country. A simple rule for FIFA to impose, not that they care.
