Netherlands coach Ronald Koeman has said that he was "lucky" after suffering a heart problem just a few weeks after his appointment with a cardiologist was postponed due to the coronavirus pandemic.

The 57-year-old underwent a "cardiac catheterisation" procedure at a hospital in Amsterdam in early May after feeling unwell following a bike ride.

"My appointment was postponed because of Covid-19. Now I wonder how many people are no longer alive because such an appointment was postponed," Koeman said on Dutch television.

"In intensive care, everything was focused on Covid-19.

"In my family, there have often been heart problems. This is why I made an appointment for 19 March. It was cancelled."

The former Southampton and Everton manager said he was always conscious and recovered quickly.

"I had chest pain, I turned white and started to sweat. I thought: 'This is not good'," he said.

"I went back to the cardiologist and everything is fine. I realise that I was lucky."
