I tihnk Reading sahould accept that Pardew is going to West Ham, arrange a decent Compensation package form West Ham and then sign up Bryan Robson as their new manager. He's good at spending money at clubs with some.
As long as Coppell stays where he is I couldn't give a flying f***.
If he's on garden leave, surely west ham will do some sort of workaround like Trevor is the manager and Pardew is doing some volunteer work in the west ham dug out while on garden leave, there's bound to be ways round it.
