Manchester United should have backed David Moyes with £150m - Allardyce

Sam Allardyce has claimed Manchester United should have handed former manager David Moyes 150 million pounds to spend in the transfer window, the amount of expenditure current boss Louis van Gaal was afforded last summer.

Since succeeding Moyes in the summer, Van Gaal has amassed just five points from as many games in what has become United's worst start to a season in Premier League history despite their lavish summer spending.

The Red Devils let slip a 3-1 lead to lose 5-3 at Leicester on Sunday, and it was the first time the club have ever lost after taking a two-goal lead in the Premier League.

And Allardyce, whose West Ham side visit Old Trafford on Saturday, feels United's capitulation at the King Power Stadium was not "normal."

"A normal United would have regrouped and won 5-3 at Leicester, not lost. You don't expect them to go under like that. Apparently they are in transition," Allardyce told The Sun. "But we've been in transition too and, while ours has been smooth, theirs hasn't. We've brought in nine new players and eight have gone out."

Van Gaal wielded the axe at United this summer with 15 players cleared out, while Radamel Falcao, Angel Di Maria, Ander Herrera, Daley Blind, Luke Shaw and Marcos Rojo all arrived.

But Allardyce has questioned why Moyes was not backed in a similar way in the transfer market by United when it came to acquiring his top targets last summer.

Allardyce -- whose West Ham side stunned Liverpool 3-1 at home on Saturday -- may be provoking Van Gaal, but he is a good friend of Moyes and thinks the club treated him badly by sacking him just eight months into a six-year contract in April.

"If I was sat at home in David's shoes I would be wondering why they didn't spend the 150 million pounds with me," said Allardyce. "There was a complacency by United in not going out and delivering the signings David felt he needed. Now there's a panic on.

"He will obviously look at what he might have done better but he should have got the players he wanted and he tells me he didn't get any of them.

"It was difficult enough taking over from [Sir] Alex Ferguson but if, when you take over, you don't get what you want, it's so much harder. It was a great shame because he'd done everything right at Everton and Sir Alex saw the fact he wanted to build at United like he had done at Everton.

"I'm not so sure anybody would have been successful in that season -- history tells you that. Look at other examples, like when Brian Clough took over from a legend in Don Revie at Leeds and only lasted 44 days."
