West Ham boss Sam Allardyce has warned that he fears a backlash from Manchester United at the weekend, after their 5-3 loss against Leicester City a week ago, as reported by The Guardian.

The Old Trafford club were 3-1 up against Leicester going into the latter stages of the game, but conceded four without reply to lose a stunning goal fest.

West Ham, on the other hand, managed a 3-1 win against pre season title contenders Liverpool, stifling Brendan Rodgers’s side to perfection.

However, Allardyce does not feel as though this will make the task any easier on Saturday, and is worried about a Man Utd side looking for revenge.

Allardyce said: “No. I’m thinking a backlash.

“I think that because of the determination of the Man United players and the fact they are playing at Old Trafford.

“I know there’s quite a lot of new players playing there but certainly the demand of Manchester United is huge and they’ll be really fired up to make sure that they try and perform like they did against QPR and beat us.

“They will be pretty down about that performance they gave at Leicester and they will be hurting and they know the only way they can put that right is to get out onto the field and punish us for it – so we will have to be careful about that.

“A draw would be great for me, anything more than a draw would be outstanding as far as I’m concerned.

“They [the West Ham players] have got to look forward to a tough game at Old Trafford now and test their skills and test their ability at a stadium that can obviously be daunting for some players.

“Hopefully our new players won’t be daunted about the prospect of playing at Old Trafford on Saturday.”

Elsewhere, the former Bolton manager has questioned the fact that Man Utd have spent £150 million this summer, when they did not back David Moyes in similar circumstances after his arrival last season.

Man Utd have won only one game this season, beating Queens Park Rangers at home.

West Ham United manager Sam Allardyce has panned Manchester United for not backing David Moyes last summer in the transfer market, as reported by the Daily Express.

The former Everton manager took charge of the club after the retirement of Alex Ferguson, and was considered to be his hand picked replacement.

He was ultimately sacked by the Manchester club after failing to put any consistent form together, leaving the club in April.

His spell lasted far less than a year, which contrasted significantly with Ferguson’s extended reign in charge of the club.

Moyes was ultimately replaced by Dutch boss Louis van Gaal, and the former Netherlands manager has been granted £150 million to spend this summer, choosing to use it on six new signings.

The West Ham boss has now questioned the logic of not giving Moyes similar support, given the size of the task he had ahead of him.

He told The Sun: “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.

“There was a complacency by United in not going out and delivering the signings David felt he needed. Now there’s a panic on.
