Former West Ham gaffer Sam Allardyce said several charities had been close to his heart during his four years at the East End club.

Taking part in BGC’s Charity Day for the third time, he was on the phones to raise cash for Muscular Dystrophy UK and took time out to reflect on the chaotic parallels between hitting the phones and the beautiful game.

“Trading is a bit like football, it’s mad,” he said.

“There are just a few moments between trading a profit or loss and just a few seconds.

“It’s a bit like being in the changing room in the stand before you go out too, because there are good vibes.

“The boys and the girls work hard and go out and have a scoop before they go home – they are good characters and what they do is remarkable.

“It’s my third year here and I’ve learned not to trade – just leave it to the professions, not the amateurs.

“Then make sure they look after you.

“I suppose all charities are close to my heart and this is giving time to have a bit of banter on the floor and raising money. It’s such a wonderful thing.”

Big Sam was one of many celebrities at BGC’s Charity Day in Canary Wharf, held in memory of those who lost their lives in the 9/11 terrorist attacks.
