I still think you won't win the title if you don't get a Giroud upgrade. He's good but he isn't a difference maker.
Who could you realistically sign, Lewandowski?
I completely agree, Giroud is seriously jeopardizing our title chances, and as things stand, i think city are the strongest team in the league really. We need to sign a striker and hope our defense stays fit, because the second choice players in defense are all rather poor(Vermaelen, Jenkinson and co), so ideally signing a centerback as cover would be fantastic.
i'm not sure who is realistic in January, Lewandowski seems like he's made up his mind and he's going to Bayern. Real look like they've missed out on suarez for this january at least, so they won't let Benzema go. I really can't think of any top strikers that we can realistically aim for this January, unless we pay really silly money. That's very worrying, because Wenger is known not to buy unless the player coming in is both an upgrade and comes at a reasonable price. Monco is mentioning Jackson Martinez, though i have no idea how good he is to be honest, or how possible it is for him to move in Jan.
To be honest, I don't see us signing a striker, and it will come back to haunt us, unless Podolski emulates his Koln form somehow.
