I am surprised by the responses in this thread. Not because we won the game (players can and should be criticised when we win) but because I thought he was quite central to how we played.
His finishing was a bit array that much is true. I don't think he missed many guilt edged chances though, it was more that he he didn't make the best of a number of half chances he had. There are some caveats as well, the one where he is slipped through from Michael Keane the ball is just a bit underhit, if you watch it he actually has to slow down to wait for the ball which means he allows the defender to get back at him. Had the ball been the right pace he's in on goal with a clear opportunity.
Likewise he was inches away on a number of occasions from connecting to crosses. He keeps improving every week. Last season he was a fair bit off being even in the right place, now he's inches away. A lot of that will come with maturity but other bits of it with familiarity with other players. In the two years in the team he's improved say 50% and he only needs another 5% in my view to be able to start flying in on those whipped in balls. IN fairness some of the time the issue was with the crosser as opposed to Calvert-Lewin himself. I'd also add, the attempt in the first half to Fabianski's near post was not a poor effort at all and there was another he took really quickly and nearly scored which again was a very good effort.
So while his finishing can be a bit hot and cold I don't feel it's as poor as people make out. Particularly with his head, his ix now extremely potent at finishing but probably needs to catch up a bit in terms of chances on the ground.
More broadly though, myself and
@Eggs were discussing the other day measuring strikers on chances/shots they get per game is as useful as measuring "finishing". He makes lots of chances for himself. No other striker in the squad gets the range of chances we made for him yesterday. While he will never be a natural goalscorer, he's improved substantially his finishing this season and if it can get a bit better he will score a reasonable amount of goals.
More broadly though, take the goals out of the game, he is central to how we want to play. His hold up play is now very good, he wins lots of high balls with his head, gives us a target off crosses and increasingly is adapting his game to run in behind. It allows for Sigurdsson to turn balls around the corner (sometimes aimlessly) and they are made something of and he gives an effective out ball for the centre backs and goalkeeper when they are stuck.
He also "transitions" the ball quickly on the counter which is central to how we play (particularly away from home). He terrified West Hams defence yesterday and in doing so gave space to other players to do the damage.
Some of Moyes's best teams did not have a prolific goalscorer, but a player up top who helped the others. I thought our best football actually came with Fellaini/Cahill up top, who caused such a menace it allowed others to prosper. Likewise our 1987 winning team didn't have a single striker scoring all the goals, but a team of attacking options and strikers who were unselfish in how they helped the team.
It wasn't a "great" game for Calvert Lewin yesterday but I was impressed with him. There are things he can do to get better but he improves game on game for me. I look back to even 6 months ago and he has come on enormously. And he contributes to the team. It's pleasing to see him timing his runs better, thats the best it's been for us. If he can continue to work on that, alongside his aerial threat he will be a real danger to opponents.
