Fahad Musanan, 24, was watching the Premier League clash with friends in Uganda when he fainted as Lampard slotted home with minutes to play.
His friends rushed him to hospital but the 24-year-old, himself a professional footballer in the Ugandan Premier League, was pronounced dead upon his arrival at Bombo Military Hospital.
"He has been a passionate fan of Chelsea and would do anything for the club," Musanan's friend Gerald Bagoole told Kawowo news agency.
"We trained with him on Sunday morning, had lunch together."
Kawowo reported: "Being a staunch Chelsea die-hard, it is believed shock might have led to his heart failure and complications."
