If Bendtner had come to Arsenal when Arteta was manager, we never would've known his name. I can barely think of a less Arteta-ish player. Talented yes, but absurdly poor vision at times, and he could barely play unless he was over the ball facing goal, and was slow-paced.
Chamakh was much maligned, you could see the player Wenger had tried to sign and the role he'd tried to fit him into, but he was psychologically brittle and was overexposed due to Van Persie's injuries—but let's not get into discussing that Dutch dog and his inner child.
