After two seasons out of Europe's premier club competition Manchester United are back in the UEFA Champions League.
Michael Carrick's side kicked their campaign off against Azerbaijani side Sabah on Thursday night, with the visitors making their own history in the process.
The game was a landmark fixture for United, with it landing exactly 70 years since the club made their first foray into European football.
Under the tutelage of the legendary Sir Matt Busby United were the first English team after win the UEFA Champions League, capturing the honour in 1968 when it was known as the European Cup.
The club has since gone on to lift the trophy on two further occasions, sealing victory with one of the most dramatic endings in all of sporting history against Bayern München in 1999, before beating Chelsea on penalties nine years later.
However, their biggest win in continental football actually came before all of the silverware in their second-ever European game.
What is Manchester United's biggest-ever European win?
Manchester United's biggest ever victory in what is now the Champions League came all the way back in 1956 when they defeated Beligan side Anderlecht 10-0.
After claiming a 2-0 victory away in Brussels, the Busby Babes had their first European home game two weeks later in the return leg.
Only, it wasn't at the club's regular Old Trafford home.
With the Theatre of Dreams not yet having floodlights installed, the game was instead played at Maine Road, the then-home of the club's bitter rivals Manchester City.
In all, more than 43,000 fans packed in to watch the showdown between the champions of England and Belgium.
Ultimately though it was barely a contest. United took the lead after just eight minutes through Tommy Taylor and had claimed a five-goal lead by half-time.
The hosts continued to punish their outmatched opposition after the interval and walked away 10-0 winners, with Taylor getting a hat-trick, Dennis Viollet scoring four, Billy Whelan notching a brace and Johnny Berry also getting on the scoresheet.
United's biggest victory in the Champions League era came more than half a century later when they claimed an iconic 7-1 win over Roma in the second leg of their 2007 quarter-final.
