Sportsmail columnist Graeme Souness played with Gianluca Vialli for two years at Sampdoria between 1984 and 1986.
He gave an interview to Sky Sports on Friday, during which he broke down when remembering his friend.
Vialli passed away on Friday afternoon at the age of 58 after a battle with aggressive pancreatic cancer.
I had only seen the news 10 minutes before and I got a call to do the interview. I did not find it easy. I said this on air, but if I had to name 10 people who had his qualities, I would struggle to do so.
