No we dont.
That's what we've just been trying to get rid of.
We need TOP class additions. The squad is has more than enough decent/versatile members..
We need some World Class additions if we want to push forward.
What you mean is. "We have to sign what I consider to be World Class additions."
We have endless conversations about who is world class and who is not, even with other team's players. No one is going to agree on who is world class, except for a few players that are unsignable. You can even argue Rooney is not world-class, someone is just arguing that in this thread.
We have to win something this year, or make such a good effort that no one can deny that the team is good enough. Wenger needs to do that, and he can sign whoever he wants, because when the dust settles, he is the one that is going to get the blame. Even if we sign Rooney and Suarez and 3 other players for 50M each, if he doesn't win, and we don't look good, no one is going to give him a free pass, because he spent a gazillion pounds. They will just rip into him more.
I don't care who he signs, or how much he spends, but even I am not going to make excuses, if we can't compete. The upside of him not spending is that if he does fail this season, then I am pretty sure he will leave, and the next man will have a good pot of cash to begin his tenure.
