I believe he does care about international football as well, but in this case the national team literally have nothing to play for while he also need to very cautious with minor injury/knocks he's had recent, It's just a matter of few day before we know what really is wrong him and whether or not he'll be available to play against Liverpool, that's surely a fixture he wouldn't want to miss, I'm very sure but you sure already know by now that Guardiola would never risk playing Haaland if he is not 100% cleared to play by the team doctors.
This is hardly news; he spends months playing for Manchester City and pretending to be injured whenever he is on international duty in order to have a solo break before returning to club football. He is dragging his country through the dirt in order to prioritise a large salary cheque.
Faked an injury during the last three international breaks, missing the majority of Norway's qualification matches. Ghosted in all of Norway's major games.
Jarrod Bowen is another player of concern having withdrawn for the England squad due to injury, the same goes for Mitoma (I'm already looking to get him out for a long term or permanently, perhaps), and Rasmus Hojlund too.
Southgate confirms Bowen injury is not a serious one, so hopefully he would return after a week rest.
