I was starting to think this also.
Now i have sat back and recovered from the end of the season, i have tried to put myself in the owners shoes ( who have a hell of a lot more riding on this than i have) and if the stories are true, i guess i can understand why they may think a change is best now.
IF they are looking to spend, would they want CW spending there money (looking back at January when they were at the club)?
A few players brought in (either loans or fees) with very very limited success.
IF CW is going to spend there money, he will go and get CW players (which is understandable as hes the boss), but if a change is made, will the money spent then be wasted as a new boss may want to play a different style?
I guess the big question is, how much confidence do the owners have in CW from the time they have been in charge.
