Zlatan Ibrahimovic made his Champions League debut on September 17, 2002. He then became a great hero when he scored two goals for Ajax against Lyon.
Just over 19 years after his debut, the 40-year-old can make history as the oldest goal scorer in Champions League history when Milan face Atletico Madrid.
The current record is held by former Roma icon Francesco Totti, who was 38 years and 59 days old when he scored his last goal in the Champions League.
But, the Swede starts the thriller match on the bench.
Milan coach Stefano Pioli chooses to start with Olivier Giroud on the attack instead of Zlatan.
The match starts at 21.00.
