He 100% needs to be more clinical and composed in front of goal, thats somthing he has to improve.
However, if him being the striker with his pace, movement and hold up play enables others to get into positions to score and the goals are spread thats just as vital. Is it better to have 3-4 players getting 10-12 goals or 1 striker getting 20 with the other 2-3 players getting 4.
Lukaku was a world class goalscorer but he never created anything for himself, his hold up play was awful, meaning the midfielders couldnt make runs as you couldnt trust him to keep possession. He didnt run the channels and basically didnt do anything physically to keep defenders occupied. Dom is the total opposite
Strikers who possess all of the above are rare and if they do exist, are playing for the top clubs.
Its an unreal expectation for us to be able to sign someone like this so we either find another proper goalscorer who may not contribute elsewhere or we stick with Dom, help him improve, work on his finishing and keep spreading the goals.
Switch them 2 strikers yesterday and I dont think we would have had 4 goals.
