In a blog post, a Hammers fan said the chants made by his fellow supporters made him "sick to my stomach".

As I type this, I am in so much anger with people who are support the same football team as me.

I have had a 'fellow supporter' calling me a Spurs fan in disguise for hitting out at the scum that sang 'viva Lazio' and it just got worse as the game went on when the scum started singing 'we'll stab who we want.'

I honestly do not understand what these people get out of it? They give our club a terrible image and I hope the FA investigates this, catches the people that was chanting and gives them lifelong bans from football.

After the game, West Ham boss Sam Allardyce said he did not hear the fans' chants.

They shouldn't be doing things like that.

If I didn't hear it I can't condemn it can I?

I will wait and look at it myself and make a comment once I have listened to what they have said.

I don't want to be a political animal, I'm here to talk about football and not what fans are saying and singing.
