One of the best qualities Haaland has is how big of a team player he is...never showing any bad energy on the pitch or towards his teammates.
Mbappe on the other hand just comes across as an egotistical prick.
IMO
He's worth the baggage though if you have the right squad and set-up around him.
PSG's problem is that they have had the likes of Mbappe, Neymar, Messi, Di Maria, Icardi, Kean etc either all together or at one stage or another. You can't carry that many egos.
If they had prime Cavani and another willing grafter in that starting line-up alongside Mbappe, I think they would have won a CL by now.
No other player could have gotten France back into that World Cup final. From when he scored that penalty, he took over the entire show and it was unreal to watch.
Anyway, it's a moot point as I think as I can only see him going to Madrid, and I think it's a perfect fit as he'll have the ego and confidence to excel, but enough top pros like Kroos, Modric, Alaba to perhaps help change his mentality.
