In a 4-4-2, sure, but Bendtner is the better player, with a better scoring and assist record, Wenger simply won't play him. He played 500 minutes this season, with 2 goals and 2 assists, with a great record in the cups Fa cup, 5 games 3 goals 4 assists, carling cup, 4 games, 3 goals.
Last season when he played ONLy when RVP got injured, he scored 6 and 5 assists in 13 starts, he started 5 champs league games with 5 goals, one of those goals away to Barca, he also set up two goals against Barca.
Wengers got this dumbass system in his head, he keeps buying players not suited to it, he will only play certain guys like Bendtner if everyone else is injured, when the other guys are fit again he puts Theo/RVP/Nasri/Song/Diaby/Sagna straight back in the team despite several of them literally being awful and a couple simply who aren't working well in their positions, RVP is anything but a lone striker.
Its simply not working, we're one of the only clubs around who are dumb enough to not rotate really at all until injuries occur, everyone else tries to prevent injuries by resting players, Wenger just leaves the bench out of form with no game time till he's forced to play them.
Sounds like we're buying ANOTHER striker, to play on the wing, when strikers is the last thing we ruddy need.
