Sir Alex Ferguson's crucial use of substitutes during Manchester United's 1999 UEFA Champions League Final win has been voted the best-ever decision in sport.
The former United boss sent on strikers Teddy Sheringham and Ole Gunnar Solskjaer with the clock running down against Bayern Munich - and both scored in injury time to win the trophy.
The Champions League-winning decision beat 49 others on a shortlist selected by Sky Sports experts.
United went into the game knowing a win would give them an unprecedented treble with the Premier League and FA Cup already in the bag. When the Germans took an early lead and looked to cling on, it seemed United would fall short. But Ferguson's canny use of substitutes proved decisive, with both scoring historic injury time goals to turn the match on its head. United won the famous trophy for the first time since 1968 and Ferguson's legendary status was sealed.
Former England and United striker Sheringham said: "The instructions from the boss when he sent me on were simple - get us back in the game. One of Sir Alex's biggest strengths as a manager was his decision making during a game. He trusted all of his players and we all knew that even if we didn't start a match, we could be called on to do a job. We may have left it late, but it is a night that I and millions of United fans will never forget."
