If you look at City they have so many players on the pitch that can make a difference in the final ball. Watched City latest game. Not only they had Halland, Foden, and Mahrez but KDB and Gundogan in the middle. They all attack the box with so much coordination, it looks very routine while our play lacks that.
Alternatively we need a ruthless attacker, which is why I think Ronaldo would make sense.
