Stuart McCall today slammed the managerial merry-go-round and declared: It's getting ridiculous.

McCall believes that too many clubs are obsessed with a quick fix which means that bosses are not getting the time to put things right.

There have been 21 changes already this season - with six Premiership hot-seats under different control since the campaign kicked off.

Paul Jewell, McCall's former chief at Valley Parade, was one of two new appointments unveiled yesterday when he took the Derby reins after a six-month sabbatical.

Alex McLeish also assumed the Birmingham reins following his decision to quit the Scotland national job.

McCall said: "Jagger's had his time out and obviously feels it's right to get back in now but he's definitely got a tough job on his hands.

"At least Derby are not cast adrift and there are a lot of teams down there with new managers, who are all trying to put their plans into place. He's signed for three and a half years and if Derby do go down then I'm sure they will come back stronger.

"But it's getting ridiculous now because managers are going into clubs and not being given the chance to rebuild. I'm not talking for myself but in general, teams aren't prepared to give the new man time to turn things round.

"You're looking at three or four games and then because of the websites and fans phone-ins, you're suddenly trying to get people out.

"Look at Sam Allardyce already getting all this stick at Newcastle.

"Then suddenly they'll go on a good run again and he'll be the best thing since sliced bread.

"Lots of things go on at a football club behind the scenes that people don't see.

"That all needs to be sorted out but you cannot expect to do that overnight.

"There are some clubs who let you get in and do things to plan for the future but others just want everything now.

"How are you going to make that progression if you are always changing the manager - it's crazy."

McCall was shocked to see Billy Davies fired by Derby only six months after taking them into the top flight with play-off glory at Wembley.

He added: "Billy's almost paying the price for being too successful. To get Derby up from where they were last season was a fantastic achievement and now he's out the door.

"It's the same with national managers. Steve McClaren had only been in charge for three games and he was getting stick from all sides.

"The lifespan of a manager is getting shorter and shorter and you just want people to be a bit more sensible."
