The problem or frustration with Barkley is that he is not completely useless, he has some talents/good attributes but hasn't been committed to fulfilling them or shown the desire to be the best he can. Joining us was supposed to be the platform for him to go to the next level, to improve himself but he's still the same inconsistent player that he was at Everton - can be good in patches but not great/consistent overall - and he's already 26 years old, he should be entering his best years. If he doesn't show any improvement ASAP, don't be surprised if Lampard decides to just cut him loose in the summer, especially with Loftus-Cheek returning and players like Gallagher impressing on loan.
