Well 3 of those joined this year, one's an injury and 4 are have been rubbish for years. We've got a HUGE damn squad, thats barely anyone, unfortunately just the people Wenger picks to be rubbish for us every game.
Chamakh because he's shown no where near his early season form(as so many new players put in extra effort, then give up) and frankly because he's on a free it would turn into good business if we sold him for 10 mil now, if we sell him for 10mil in 2-3 more seasons, thats 4mil a year wages so 10mil a year will break even, may aswell sell him now and make a 6-7mil profit. Offers nothing new, isn't brilliant, not great in the air, not fantastic but not at all bad with his feet, just doesn't seem to be up for the fight in this league.
Sagna, 9 months, best right back in the league, since then, rubbish, theres been so many bad passes I forget which, was it a Barca or a Birmingham goal he caused with a woeful woeful pass.
Oh, and for anyone who thinks Nasri is better than Arshavin........ you're stupid. Our best player this season by a mile(due to Fab/RVP injuries).
