West Ham United boss Sam Allardyce has called for professionalism from his side as they travel to Bristol City in the FA Cup.

Saturday's results saw Tottenham Hotspur, Manchester City, Chelsea and Southampton all knocked out while, Manchester United and Liverpool were held to draws against Cambridge United and Bolton Wanderers respectively.

"I think it's probably been the most astounding weekend ever on the basis of how many big boys have gone under and today it's about us making sure we're not a victim of it," Allardyce told BBC Sport ahead of the Hammers' visit to the League One high-flyers.

"We need to be professional. Bristol are playing exceptionally well but hopefully we're good enough to beat them.

"Hopefully we can talk about [our chances] if we win today. It'd be shame if we missed out after our efforts against Everton."
