Martin Keown highlights the big obstacle West Ham face against Manchester United

The pundit has been discussing West Ham's upcoming clash with Manchester United.

Martin Keown believes Louis van Gaal's 'cautious' approach at Manchester United will help them against West Ham United this weekend, according to his regular 'Tackle Keown' Q & A on the Daily Mail website.

Indeed, West Ham face United in the Premier League knowing they have already claimed several big scalps this season.

But Keown told the Mail: "I know West Ham fans won't like to hear me say it but it [an away win] seems unlikely. They’re suffering hugely with the loss of Dimitri Payet to injury and Manchester United are far too cautious in their style to let West Ham beat them at home.

"Everybody wants United to be expansive and has called for Louis van Gaal to let his players off the leash, but this might actually be a game when you want the Dutchman to be cautious.

"That's purely because he knows what West Ham have done away from home this season, beating Arsenal, Liverpool and Man City."

It's a fair point and West Brom showed that West Ham can be stifled last weekend. It's intriguing that Manchester United can be compared to the Baggies but that's exactly what Van Gaal has built at Old Trafford.

It may be frustrating for neutrals and purists - while even the most practical football men would probably admit this United side are boring - but, ultimately, Van Gaal is sticking to the mantra that football is all about winning.

Slowing the game up and shutting West Ham's creativity down will certainly help Manchester United and, without the likes of Diafra Sakho and Dimitri Payet, it will be very difficult indeed for the Hammers to replicate their success on the road against Arsenal, Liverpool and Manchester City here at Old Trafford.
