It was always shocking to me that people were writing this signing off. Just a couple of months earlier he was pivotal in Real Madrid winning the Champions League. Anyone who watches La Liga and Madrid knows how good this guy is. Souness clearly does not watch football outside the Premier League, he is woefully misinformed about players outside the league. He reverts to flashcard punditry, usually based around bashing "Johnny Foreigner". Souness also has a habit of basing his punditry on something negative that may happen in the future instead of what the player represents at the moment. He based his whole defence of Ronaldo on a fictional conversation that he insists Ronaldo must have had with ETH. No evidence or inside sources, but he is convinced this conversation happened and even knows the basic words that were spoken. Souness is a proper weapon and should be avoided at all costs.
Anyway, back to Casemiro. He is sublime and it is so good to finally see a top player who is still world-class and actually wants to play for United for football reasons.
