Former Rangers star Ugo Ehiogu has died at the age of 44.
Ehiogu collapsed at Tottenham's training centre on Thursday after suffering a cardiac arrest.
Ehiogu, 44, who scored the winning goal – his first for the Ibrox club – in a 1-0 defeat of Celtic in 2007, had been overseeing the club’s under-23s.
The announcement of his passing was made on Twitter by Tottenham Hotspur.
The Football Association has led tributes as they begin to pour in.
The tribute on the official @England Twitter account read: "We're devastated to hear the news that Ugo Ehiogu has passed away. Our thoughts and sympathies are with all lucky enough to know him."
Ehiogu's former club Villa, for whom he played more than 300 games, tweeted: "We are deeply saddened to hear of the death of our former defender Ugo Ehiogu.
"Our thoughts are with his family at this terribly sad time."
The club added: "We will be holding a minute's applause before our derby with @BCFC...
"Both sets of players will wear black armbands as a mark of respect."
Ehiogu, who made 200 appearances for Aston Villa between 1991 and 2000, wining the League Cup spent seven years at Middles-brough, where he also won the trophy.
He won four England caps and was signed by then Rangers manager Walter Smith in 2007.
His Old Firm overhead kick goal in April of that year was voted goal of the season by fans. He also played for West Bromwich Albion, Leeds and Sheffield United before retiring in 2009.
