Because Man City have nothing to prove. They can effectively sign who they want.
We have loads to prove, hence the spotlight is on us when all we can muster is 'making moves' rather than making actual bids.
Right so you're completely ignoring the fact it's taking them (an apparent huge club) the same length of time to sign a player as us and for some reason we're classed as slow and useless re: transfers. Point to prove or not, time is time.
