That's the thing we're not going to go all out for a centre forward, I doubt he will be replaced at all, We're going to lose a player in our squad who can score goals, that's it.Those two players would start over Podolski that's why Wenger is letting him leave. He's not very good and only contributes goals nothing else. With Walcott back we don't really need him around anymore. Should go all out for a CF now.
If Wenger replaces him I will eat my words but I wouldn't bank on it if I were you.
