Chelsea striker Diego Costa was filmed by David Luiz drinking beer in the dressing room after Chelsea’s 1-0 victory against West Brom on Sunday.

Chelsea boss Antonio Conte insists a bottle of beer immediately after games is perfect for rehydration from 90 minutes of punishing Premier League football.

Conte said: “After the game, for rehydration, you can drink Coca-Cola, one beer.

“It’s good for recovery. But one, not a lot.

“It’s good after you finish the game, quickly, not an hour after the end.”
