50 is a magic number and Juventus' last 16 first leg game with Lyon will mean one Juve player will reach this landmark.
It is the midfielder Juan Guillermo Cuadrado. The Colombian had played 49 matches in European competition up to now with Fiorentina, Chelsea and Juventus so starting against the French side is special for him.
Cuadrado made his European competition debut on 22nd August 2013 for Fiorentina in the Europa League against Grasshopper in Switzerland. The Italians won that game 1-2 and Cuadrado scored. Since then, he has not stopped shining in Europe.
Up to now, the Colombian has played 13 Europa League games, all of them with the Italian side and 36 Champions League games: 35 for Juventus and one for Chelsea against PSG in 2015. He has scored eight goals and won 29 of those games. He got 11 draws and nine losses.
