Manchester United's Mason Greenwood celebrates his goal. "Sending them home happy was as pleasing to me as winning the game with the players".
From that very first game we showed what we can do and played the way we know we can play.
The circumstances and the way we did it, just makes it that bit more special.
Celtic, who won against the Italian outfit at Parkhead, earned a dramatic 2-1 victory in Italy and booked their place in the last knockout stages of the competition.

But substitute Ntcham latched onto Odsonne Edouard's pass in the fifth minute of added time and dinked a cool finish over Lazio goalkeeper Thomas Strakosha.
Off the pitch, there were sadly more incidents, with another Celtic fan stabbed on Thursday after the game, and it's clear everyone on this side of the Channel will be glad these matchups are over, so maybe it's time for certain Lazio ultras to put their hands down and use them to pray for their team's qualification out of Group E.
The German club moved second in Group J, ahead of Roma on head-to-head and two points behind leaders Istanbul Basaksehir, who saw off 10-man Wolfsberger 3-0 in Austria.

Forster also revealed that Celtic will now be aiming to top their group.
A hat-trick for Sevilla's Munir El Haddadi was supplemented by two goals from Munas Dabbur in a 5-2 away drubbing of Luxembourg's Dudelange as the Spaniards kept up their 100% record in Group A after racing into a 4-0 halftime lead.
No Celtic team had won in Italy before so it is an incredible achievement and fantastic to qualify out the group already.
