Then why isn't he doing all of that stuff, firstly, in training and secondly when he plays?
Because if he was as prolific as he was in the past he'd be playing all the time and scoring all the time, right?
I'd love it if he was. Just can't see it coming back in time for him to save his career, here.
Roberto Firmino has started in 29 games and has scored 9 goals. Sturridge has started what? 9 games and he has 6 goals to his name.
He is not starting because he cannot score, he is simply not starting because the manager does not fancy him. By the way, here is a list of players who have more goals and assists that Roberto Firmino this season:
Hueng-Min Son, Dele Alli, Harry Kane, Ericksen, Diego Costa, Eden Hazard, Pedro, Aguero, Sterling, De Bruyne, Ibrahimovic, Sanchez, Walcott, Ozil, Giroud, Lukaku, Defoe, Mane.
Then you have a group of players who would most likely outperform him if they played the minutes he has played i.e Rooney, Mata, Rashford, Martial, Chamberlain, Lucas Perez, Fabregas.
In all this, people are arguing that Sturridge isn't as prolific, he has lost a yard of pace. He misses some chances he should convert as does everyone, but by and large, he is the best striker at LFC and that has been sacrificed for what? Increased work rate and less potency up top?
This team is most likely going to be in Europe next term, that will mean more games at a faster frequency, and I would love to see better teams than what Klopp was fielding in some of the cup games this season. For that you will need depth, and selling one of the better players in the team to replace with lesser quality does not make any sense. You could have Origi, but he is so hit and miss that it boggles the mind; one day he shows immense promise, the next game he struggles with decision making to the extreme.
