£10m is not a pittance; our entire club's wage bill was £120m last results. £10m on a player who has never played in the league before, has just come back from injury, barely played last season and would have no sell on value because he wouldn't be our player.
I wanted Sahin but not for £10m for a single year; it's crazy money and a very high risk proposition. That kind of money gets you Giroud and Podolski, and what if he takes a couple of months to get going?
You don't need to get slightly mugged to be a successful club, in fact you generally try to avoid getting mugged in any walk of life if you want to be successful.
