Babel is not a good player, but he has all the ingredients to be a good player and under a manager with more ability with younger players he may be good
Also, in regard to the above post, as an Arsenal fan I think Song is one of the most important players at the club at the moment and I'm dreading the time when he leaves for the ACoN. He has been in brilliant form this year and I don't know which games people who complain about him have been watching this year. He's always in the right place, makes so many crucial tackles week after week after week and is so strong, shrugs soo many players off the ball. There's one thing I'm critical of him about and that's his speed. Other than that though, I think he's a brilliant player and I implore anybody to name a 21 year old DM playing to his standard every week at this kind of level.
As is common with many football fans (and an area where Song suffers) is that people often comment on him without giving him enough viewing, and because he's Song and not Mascherano/Essien he gets lots of criticism for some odd reason, for me he's been far better than Masch this season and up there with Essien. On current form you'd have to spend £20m to find a better player than Song (look at Melo, nearly £20m and he's been garbage at Juve, phew) who is technically good enough to suit this team
