He was very
good in
19/20, and had a really
good 20/21 too. Crazy if you think otherwise, checkout the links, the praise was almost unanimous. He's not world class, but he's a solid 7/10 player. Its not a surprise he is selected over Fabinho for the Brazil National team. Lots of people were nominating him for most improved player in both 19/20 and 20/21. His stats also tell you that.
Not too long ago, many people on redcafe were calling him as good as Kante. He is a proper box to box midfielder. His energy is something we miss when dont play him, and he's a good ball winner(on the press), and quick to release the ball as well. Often in matches where we set up to counter its particularly effective, as he plays line breaking passes, and is better on the ball compared to McT. There's a reason him and McT were our first choice last season. Your point about savvy teams is bogus, because his best games for us have come against the likes of City, Liverpool, PSG etc.
Is he a limited player? Yes. Is he a first XI player player for a title winning team? Probably not. But that doesnt mean he is crap. He is a good midfielder and has put in a lot of good performances for us, deserves to be in our squad, and anyone saying otherwise probably doesnt watch us play regularly.
