Pep Guardiola has joked that managing against Vincent Kompany makes him feel old.
The Manchester City boss comes up against his former captain as Kompany's Burnley visit the Etihad Stadium in the FA Cup quarter-finals on Saturday.
Kompany, who left City in 2019, has made a huge impact since taking charge of Championship Burnley last summer.
Guardiola, 52, said: 'He was an incredible figure here. He is one of the biggest legends I have had.
'But I am a little bit concerned because when you start to play a game against a player you had on the touchline, you realise how old you are becoming!'
Burnley are 13 points clear at the top of the Championship as they close in on a return to the Premier League.
Guardiola said: 'From what I have seen, I'm not surprised at all with their position or what they have done in the Championship.
'They will be a really tough opponent because they do incredible things on the pitch.'
Kompany captained Guardiola's City side until his departure at the end of the triumphant 2018-19 campaign.
Together, they won two Premier League crowns, two League Cups and an FA Cup.
