West Ham United boss Sam Allardyce wants Andy Carroll to play smarter.

He wrote in the London Evening Standard: "Andy Carroll (against Swansea City) rightly took the headlines with his two goals and - going forward - both we and he himself have to manage his physicality carefully.

"I have said I want him to be careful with the way he goes in at times but ultimately it will be Andy who makes that decision.

"As a young defender, I used to challenge for balls I was never going to win. Then, smash, bang, wallop - I would have a broken nose or a gashed head.

"Experience taught me to assess things more carefully. I would still shout "Sam's up" to fool the striker but then drop off to try and win the flick-on.

"That's how you learn, you need to retain the information and if Andy can do that, he'll be his own best judge of what he can and can't do.

"You have to remember that although Andy has been around for a few years, sadly too much of the time he's been on the treatment table. You're not gaining the experience if you're injured."
