The problem with Ronaldo was that at his later age, he could be an asset, used correctly, that's why the last season at juventus under pirlo, then here under ole, then rangnick who were all essentially amateur coaches at best. He required proper time management, not playing every week, and playing to his strengths. He was clearly still talented enough to offer something last season. Both home and away against spurs and arsenal he was good. He scored a number of last minute winners/equalisers in the champions league.
But he posed some tactical limitations as well, not least that he was never a number 9 and thats where ole played him, and it doesn't really suit him. If we'd had ten hag last season when we signed him before he was run into the ground playing 3 games a week at 37 years old in the most physically demanding league in the world it would have gone much better.
I don't buy all this ruining the vibes stuff until this year, you could see last season elanga and a lot of the other younger players idolised him, and he's been described as having a great work ethic and the like at every other club. This season obviously it did become toxic
