When you think about what Vincent Kompany has been through, with the number of times he's had to come back from injuries, it is remarkable that he is even out there.
Yet at the Etihad Stadium he was like Peter Pan, a player reborn, free of his previous problems, floating around the pitch with ease and becoming the man of the moment for Manchester City.
That goal might well win City the title. He opened the door for them when they were up against a really stubborn Leicester side.
City's Premier League win percentage with and without Kompany shows how important he is. With him in the team this season, they have won 93.8 per cent of their matches. Without him, it is 76.2 per cent.
While watching this match, I said it would take something special to break down the visitors. Brendan Rodgers, the former Liverpool manager, set up a team who knew their roles inside out.
Wilfred Ndidi was in the centre, winning duels, committing tackles and making interceptions. Hamza Choudhury and Youri Tielemans were alongside him in midfield and they were helping their defence.
City may have feared this would not be their day. Then Kompany popped up with his first goal of the season.
