On not being that good this season, is this not part of being burnt out? For a large period of the season, he carried the burden for Liverpool. Rodgers played him in almost every match, he was brought off the bench against Villa when he didn't start with the expectation that he'd turn everything around on his own, he had to play a long stretch of the season out of position because Liverpool had no strikers and then bits of the season at wing back. It's easy to forget that he's still only 20 and putting so much physical and mental pressure on a player can break them. For half of last season, he wasn't getting in the team and there was talk of 'second season syndrome' and possibly being loaned out. It's only in the second half that things clicked for him and he made an impact, because he was fresh and surrounded by good players. By his own admission, he's been tired this season and shockingly he's looked laboured as a result.
People will say if he goes to City or Chelsea, he won't play as much. But I think that'll be a bit better for his development than being overplayed. At least at a team like City, he'll have Aguero, Silva et al to share the pressure like he had Suarez and Sturridge last season, and he can work on refining his talent further.
