Without knowing either personally it’s hard to be definitive but Haarland seems quite humble and a team player - so he looks like he’d fit right in at City. Mbappe has an ego the size of a planet and refers to himself in the third person WTF ! Not sure how he’d fit in at City. It’s all academic because Mbappe wouldn’t entertain us anyway - he thinks he’s bigger and better than us but Haarland I think we’ve got a fighting chance.
This is a fair point as off the field activity, personality etc is taken into account as much as footballing skill at city; there have been a number of potential very high profile signings that have apparently been knocked back based on a ‘showman like’ off field party life.
