I find these comparisons a little tedious. I'm as tired with the club's policy as much as any other person but lets think a bit. As soon as you offer one player a big salary, everyone else on a good run of form will want the same. If you give Van Persie £200k, you have to give Cazorla something similar. When Wilshere starts playing a few games, he's wondering why he isn't on that money. One of them doesn't pay off long-run (ala Arshavin - started brilliantly...now shit) you're stuck for the next 3 years paying over £120k to someone you don't want.
I don't think Theo is going to be a special player. But I think he is going to be a very useful player. Someone who will get around 20 goals playing up front or 15 goals from out wide. Someone who will frustrate and delight in equal doses...but they can't all be superstars and Theo easily looks good enough to play a role for us atm.
I would love for us to keep Theo but it's not going to happen. I hate how the board are lining their own pockets but giving Theo want he wants (i.e. what he's going to get at Chelsea and Man City) is a recipe for disaster, it truly is. We've missed our opportunity to sign him up on reasonable terms and we're paying the price for it.
