Jose Mourinho once said 'when you enjoy what you do, you don’t lose your hair' in reference to Manchester City manager Pep Guardiola.
And you can see why the former Barcelona boss is known for his attention to detail as he was seen coaching Raheem Sterling just minutes after City's 6-0 FA Cup final victory.
Guardiola was lecturing Sterling, who scored twice and nearly scored a hat-trick against Watford on Sunday, whilst the City star had his medal in his hands during the celebrations on the pitch.
The pair were debating back and forth for around a minute despite becoming the first men's team in England to win the domestic treble.
The City boss explained the incident to BT Sport: 'During the game i said something, he didn’t understand what i was saying.
'We won the league by one point so the distance to our contender is not big. I think we can do better.
'We’re gonna come back and try it again, be there to the end and try and win the title.'
Raheem Sterling explained in more detail of what it is like to work under Guardiola on a daily basis.
Sterling told BT Sport: 'The first thing we came in from the World Cup and in pre-season, his mentality was straight on it again to retake the Premier League again, go again and not slip up.
'He brought fines in. Any little thing he was fining us. Keeping me on my toes.
'The majority of the time there was times I was playing and never had competition, but every summer he’s gone in and added another player.
'I’ve been on holiday and made me think it’s gonna be another tough season. Just keep improving myself week in and week out.'
