A minute's silence was held for Diego Maradona at every European game while his old club Boca Juniors called off the Copa Libertadores game with Internacional.
UEFA was quick to respond to news of the death of Diego Maradona by announcing that a minute's silence will be held in memory of the Argentine great at all of this week's European matches.
Meanwhile, the Copa Libertadores game between Maradona's former club Boca Juniors and Brazil's Internacional was postponed on Wednesday following the news that Boca's favourite son had passed away following a heart attack.
The minute's silence was first held in the two early Champions League matches between Olympiacos and Manchester City in Athens and Borussia Monchengladbach against Shakhtar Donetsk in Gladbach, after instructions from UEFA president Aleksander Ceferin.
Ceferin said. "I was in touch recently to wish Diego well, and this news comes as a considerable shock to me.
"He achieved greatness as a wonderful player with a genius and charisma of his own."
Maradona's spokesman, Sebastian Sanchi, said the former World Cup winner died of a heart attack, two weeks after being released from a hospital in Buenos Aires following brain surgery.
South America's governing soccer body CONMEBOL said the decision to call off the Copa Libertadores game was made because of Maradona's "close connection with the Argentine club" Boca.
He played there between 1981-82 and returned in 1995 to see out the last years of his career.
The first leg of the round-of-16 game in Porto Alegre, in Southern Brazil, will instead be played on December 2.
