The more I read about the history of football, the more it becomes obvious that people have become terminally impatient for results - and it all comes down to the incredible amount of money in the game these days. The Premier League/Blatter FIFA model has done this to us.
People talk of a new manager "building a system" or a club in a state of "rebuilding" - but the reality is that there is no time for such luxuries anymore. Managers have to fashion success out of the previous managers' squad plus maybe a couple new players who have no time to adjust to their new team/system/living conditions. There is very little time to really "build" anything.
Giggs as Gaffer at Man Utd: a total disaster in the making. Giggs was a great player. We know next to nothing about his managerial abilities, and Man Utd is not an appropriate place to start one's management career. I'd love to see it happen for the drama value but it would not be good for the club (or for Giggs).
Firmino and Origi may both yet come good - they have the ability and Firmino has proven he can do it, albeit in the BL. Benteke has also proven his worth, and if Klopp used Immobile (great name for a footballer!) as a target man than he should know how to use Benteke.
