I believe most Cardiff City fans are expecting too much far to quickly from this new appointment.
You need to build a squad of players who play as a team, this might take up to 5 seasons minimum to complete. you might have to suffer the indignity of a relegation or 2 before you can move full steam ahead in the right direction.
This season for you lot has to be all about survival, you need to re establish yourselves as a championship side, if your lucky and can avoid the drop this should take around 3 seasons.
You need to forget about the premiership for the time being as lets be honest you are not going to get promoted, set your targets 5-10 years then build that squad and eventually you might fulfill your dreams.
Good luck.
