Leicester City manager Claudio Ranieri has confirmed that he sometimes rings an imaginary bell in training if he feels that his players are drifting off.
Earlier this week, Foxes midfielder Danny Drinkwater revealed the technique and Ranieri was presented with a bell by reporters at today's press conference ahead of the Premier League match away at Watford tomorrow.
Ranieri, who confirmed that star midfielder N'Golo Kante could return from injury at Vicarage Road, said: "I tell them dilly-ding, dilly-dong, when they are sleeping! Then I bought them a little bell.
"From the beginning, when something was wrong, I said 'dilly-ding, dilly-dong, wake up' during training sessions. So on Christmas Day, I bought for the players a little bell."
Ranieri's side are three points clear at the top of the Premier League with 10 games of the season remaining.
