Muhammad Ali's legendary trainer Angelo Dundee has died in Tampa, Florida. He was 90.

Dundee, the iconic motivator who famously worked the corner of Muhammad Ali for 20 years and helped Sugar Ray Leonard win his biggest bout, is said to have died of a heart attack after being admitted into hospital with a blood clot.

Dundee, was the man who guided three-time heavyweight champion Ali through many of his greatest fights including the legendary Rumble in the Jungle against George Foreman in 1974.

However, the Philadelphia-born trainer and confidant's boxing achievements were not just restricted to Ali's glory.

During the course of his career, Dundee worked with 15 world champions and was credited with helping big names including Willie Pastrano, Jose Napoles, Jimmy Ellis and George Foreman achieve their boxing success.

After starting from humble beginnings as Carmen Basilio's cutman, he went on to become an ambassador as well as a figure of integrity in boxing. He was inducted into the International Boxing Hall of Fame in 1994.

His son, Jimmy, said his father died surrounded by his family just weeks after attending the 70th birthday celebrations of his close friend Ali.

Jimmy said: "He was very happy that he got to celebrate Ali's birthday and that he got to go to the Hall of Fame. He still had much to do but led a full and extraordinary life.

The Miami Herald reported that Dundee was taken to hospital for a blood clot before returning to his apartment.

His son said: "He was coming along good and then he started to have breathing problems. My wife was with him at the time and called and said he can't breathe. We all got over there. All the grandkids were there. He didn't want to go slowly."

He is survived by a son and daughter, six grandchildren and a great grandchild.
