But the point still stands doesn't it. It's weird when people act like it's unreasonable for fans to expect players to come in and have an impact. It's not unreasonable at all, it's normal. If we sign a 21/22 year old midfielder who can't get into the side, has disciplinary issues, and struggles to make an impact when they get on the pitch, then yes, people will question it. If we sign one who does a competent job while hinting at having the ability to do more as they develop then people won't. There's no conspiracy or anything, people just want the team to get better and want evidence that it's happening.
Signing Doucoure and Allan would seem like a bit of overkill on the 'do a job for a few years' front, particularly when we already have Gomes, Delph etc. If thats the way the club want to go then so be it, but i'd agree that personally i'd rather it was one of them and a younger player with more long term value to the club.
