What's the point of keeping money for January you ask? Well I'll give you the answer Valley, the season is for 9 months not 4! We are not a club that has unlimited money that can sit on players like Man City or similar. We have to be wise with the money we have! And in case it's passed you by, most of the pundits were saying the players were over inflated now, I mean £26m West Brom wanted for that player!
As for your last questions, we have replaced Gylfi with the players coming in, that is what a club with limited resources can do, sometimes these transfers work sometimes they don't! As for the defence, whilst it would be nice to get other players in, it hasn't happened so we live on what we have.
My opinion is that you need a reality check, and realise we don't have bottomless pit of money, the money you think is left over must be used in the next transfer window, if we spent it all now, where would the money come from for that window?
