Leicester City manager Claudio Ranieri says he will “kill” his players if their title party turns into a hangover on Saturday.
The Foxes will celebrate in front of their fans at the King Power Stadium after becoming champions on Monday.
Players toasted the title at Jamie Vardy’s home when rivals Tottenham could only draw at Chelsea.
They only got back into training for today’s match with Everton on Thursday, after being given an extra day off to enjoy their triumph.
When Leicester won promotion three seasons ago their 21-game unbeaten run ended with a 4-1 home defeat by Brighton three days later.
Then-boss Nigel Pearson said players appeared to be the worse for wear and substituted Anthony Knockaert at half-time then Riyad Mahrez later on.
Leonardo Ulloa, playing for Albion at the time, scored twice in the win to help earn a move to the Premier League new boys.
Ranieri is anxious to avoid a repeat with the eyes of the world watching Leicester’s coronation.
The Italian said: “They lost, yes, somebody told me. If it happens again, I will kill them with my hands.
“They enjoy celebrating of course, it is a great achievement for everybody. I am very happy when I see the city and the fans happy too.
“But the players trained very well on Thursday and I’m expecting a very good match on Saturday against Everton.
“I watched how they trained on Thursday. It was good. It is important to clean our minds and keep going with our jobs. This is very sweet, but our job is to play.”
