6) Antonio Conte
The 2017/18 season clearly did not go to plan for Antonio Conte and Chelsea. The defending Premier League champions were dethroned and the Blues were never really in the title race, let alone the top four race.
So there wasn't much to celebrate but all it took was one phone call to make Conte laugh again. He had been a picture of resignation over many months and it was a rare occasion to see him smile and laugh.
At the press conference ahead of the FA Cup semi-final, Conte's press conference was interrupted by a phone call from his wife. His expression when he realises his phone was not in silent mode is priceless!
The Italian manager immediately apologises and was even ready to accept a fine because he admitted he would be annoyed too if it happened to someone else. One reporter even suggests his wife had called to ask him to bring home some milk, eliciting laughter from everyone present.
