Lookman is the new deulofeu. People want him on the pitch then moan when he's average then forget he is when he doesn't play. Rinse and repeat
Except with Deulofeu if you had him on the pitch for 30 minutes you knew you'd get a chance or two created from him, even with plenty of frustrating moments, lack of effort to help defensively and probably be knackered by the end but he pretty much guaranteed chance creation. If he played 60-75 minutes you'd get 3+ chances in the game from him so it was a toss up of do you put up with his weaknesses for the productivity he brought.
With Lookman we havent seen, could argue havent had chance to, if he can consistently create chances or get into goalscoring positions, take chances well etc. I would be using him more off the bench than we have been because he is different and how lifeless we have been sometimes you need that type of player. But I dont go along with the view a lot seem to have that he will automatically solve problems because we as fans purely havent seen in the games he has played that he will do what people are expecting regularly right now.
I wouldnt be considering selling him because there is a lot of natural talent there for someone to bring out, however I think the clamour for him to start is based on what people want him to be or could become than what he is right now in my opinion.
