Right, but Ribery isn't a striker, which proves my point. Neither is Müller who was even better last season. Mandzukic is though. He scored exactly half as many goals last season as Gomez managed the season before that. He's one of the best buys Bayern have ever made, and it's not because he's this unbelievable footballer who can do stuff mortal men only dream about. He's just a fairly limited, hard-working player with good linkup play and off-the-ball movement who doesn't get in the way.
Like I said, plenty of work to be done at Arsenal if you want to sign better players and improve the team. No need to spunk it all on Suarez who isn't that good a fit anyway, just because you need a better striker and he's the only one possibly available in the window who is perceived as 'world class'.
