Former Aston Villa, Middlesbrough and England defender died on Friday morning at the age of 44, following a cardiac arrest.
The Tottenham Hotspur U23s coach collapsed in training on Thursday and spent the night in hospital, before passing away in the early hours of the morning.
Ehiogu enjoyed a long and successful playing career in the Premier League, where he made 335 appearances, and was named in the 1996 PFA Team of the Year.
The former centre back won also three League Cups, two with Villa and one for Boro, and scored one international goal in four senior caps during a 3-0 win over Spain in 2001 - Sven Goran Eriksson's first game as England manager.
Ehiogu also spent time with West Brom, Leeds, Sheffield United and Rangers (where he scored a spectacular overhead winner in the Old Firm derby) before hanging up his boots in 2009. He began coaching at Tottenham in 2014.
As a much loved and respected figure in the world of football the tributes have poured in from all those touched by Ehiogu as a coach, player and a friend.

Shocked & really sad to hear about Ugo Ehiogu. Spent many a night out in @Boro back in the day, loved his music as much as his football.
