Ancelotti pointed towards the many famous comebacks that have happened over two legs in the Champions League. Most famously, Barcelona overturned a 4-0 defeat against PSG in the first leg of the round of 16 in 2017, by beating the French side 6-1 at Camp Nou. The tie is responsible for the term 'remontada', meaning comeback in Spanish, becoming popular parlance in world football.
Ancelotti said: "Remontada? We will try. It happened many times. We will try until the last minute."
