Why do all you City fans think that?
Ireland is valued at about £9M-£11M, something like that. Milner is about £18M, so it is quite clear who is getting the better deal. Ireland will mould nicely into Villa's current setup. Milner, however, is another question.
Valued by whom? Personally I like Ireland, but as an attacking central midfielder, City dont really use players in that position under Mancini which is why he has hardly played. Where as Milner is a wide player who I believe will play on the right going on the formation that City used against Spurs on saturday but with Milner instead of SWP. I think its a good signing personally.
