Nigel Pearson has slammed the decision to sack Sam Allardyce, insisting Newcastle United's rulers have undone the good work that was being done behind the scenes.

Pearson said: "I have seen the hard work that has been done behind the scenes. That work has been put in for the long-term future. At a club like this the foundations have to be right."

Allardyce's former No 2 added: "The fans at this club want stability.

"I have been part of a regime which wanted to weather this storm, come out the other side, and affect long-term change.

"Potentially, this is a big club. But there is a long way to go before it gets back up there."

Pearson took charge as Toon were stuffed 6-0 by Manchester United on Saturday. He said: "I remember when Alex Ferguson was supposed to be just a couple of games from the sack.

"Now he has been there 21 years and look at what has been achieved.

"I feel very disappointed for Sam. He had a long-term vision. Now we're in the transfer window without a manager."
