Former Premier League ref Graham Poll says Liverpool are out of the FA Cup due to Howard Webb.
Poll wrote in the Daily Mail: "Liverpool were denied a clear penalty and likely equaliser when referee Howard Webb refused them their second penalty in a pulsating Cup tie.
"Alex Oxlade-Chamberlain clattered through Luis Suarez, with Webb perfectly placed to see the offence. Suarez's theatrical 'dive' will not have helped nor did the fact that Webb had already awarded Liverpool a penalty.
"Those who have not been in such a pressure-cooker situation would not understand that, but I do.
"Webb, of course, with his experience and pedigree, should do better and be above such weakness - Liverpool are now out of the FA Cup because he wasn't."
