The Tottenham manager sympathises with West Ham after Andy Carroll's ban was upheld and believes more should be done to punish players who feign injury
Sherwood has expressed sympathy with West Ham, who have been unsuccessful in their bid to overturn Andy Carroll's red card against Swansea City last weekend.
Carroll was dismissed - and subsequently suspended for three matches - following an altercation with Chico Flores, but West Ham claimed that the Swansea defender over-reacted to the incident, and Sherwood believes players caught play-acting should be punished retrospectively.
"I think it makes it clear that Andy Carroll is vitally important to West Ham's future," said Sherwood, speaking ahead of his side's Premier League clash with Everton on Sunday.
"West Ham feel aggrieved that it hasn't been overturned. We made an appeal with Danny Rose [following his sending off against Manchester City] and we got that one overturned and I think that was unanimous.
"One thing I would say is the feigning of injury from players is something we want to keep out of the game.
"Retrospectively, I would go back and punish the player who is diving around more than the player causing the offence.
"I think that is the only way you are going to ever cut it out, to go back and give them a higher punishment."
