Middlesbrough Football Club chairman Steve Gibson has spoken of his shock and sadness at the passing of "a great man" after the tragic news broke on Friday morning.

The Boro chairman said: "I'm deeply shocked. Ugo was one of our heroes at Cardiff when the club won its only ever major trophy. 

"Ugo and Gareth Southgate were the rock on which Steve McClaren brought the club its best period in its history. 

"He wasn't just a good footballer, he was a great man. 

"It's so sudden and so shocking, my deepest sympathies go to his family and all who knew him. 

"I would regularly bump into Ugo. Football is a small world and he was always warm, friendly and welcoming. All of Middlesbrough Football Club will miss him."
