United get their 22nd Champions League campaign under way on Wednesday as we face the unknown quantity of Swiss champions BSC Young Boys of Bern.
It's a first ever competitive meeting between the sides, but just who are the group stage debutants from the Swiss capital? Here's everything you need to know to bring you up to speed in our handy guide.
The midweek clash will represent our very first competitive meeting with
Young Boys. The two clubs were actually drawn against each other in
1958/59 but, when officials ruled against United's invited participation
in the European Cup and gave Young Boys a bye to the next round, the
sides played home and away friendlies. The Reds won 3-0 at Old Trafford
on 1 October 1958, after losing 2-0 in Switzerland on 24 September.
Gerardo Seoane guided FC Luzern to third place in the Swiss Super
League, which was made more impressive by the fact the team were
threatened by relegation when he took over the reins in January this
year. Just five months later, the 39-year-old became Young Boys boss,
succeeding Adi Hutter, who replaced Niko Kovac at German club Frankfurt
following his departure to Bayern Munich. Seoane, who also spent the
majority of his playing career as a midfielder in Switzerland, has hit
the ground running in Bern and will be hoping his Young Boys can cause
an upset or two during their maiden experience of the Champions League
There's a certain poetry about a team named Young Boys plying their trade at a stadium called The Wankdorf - or, to give it its full name, the Stade de Suisse de Wankdorf. The second largest venue in the country, it has served as the club's home since 2005 and has a capacity of just over 32,000, also serving as a Euro 2008 venue and the Switzerland national side.
Like most Swiss teams who begin to capture the attention of the
continent, Young Boys have a habit of losing their best players to the
Bundesliga. The most recent example is defender Kasim Adams, who was
snapped up by Hoffenheim in the transfer window.
That said, their weapons remain formidable enough to give
Mourinho plenty to ponder. Arguably their biggest goal threat is the man
who broke the deadlock in that Everton game three years ago game:
The 34-year-old former Paris Saint-Germain striker scored 15 times in
20 starts last season in tandem with Cameroonian international Jean - Pierre Nsame.
Rght-back Kevin Mbabu is also one to watch. The former
Newcastle United man is improving rapidly in Bern and made his
Switzerland debut in the 6-0 Nations League thrashing of Iceland last
week, deputising for Arsenal's Stephan Lichtsteiner.
Ex-Ajax and Benfica midfielder Miralem Sulejmani will be a real
danger down the left, too. With two goals and five assists in eight
appearances this term, Young Boys will hope the Serbia international is
fully fit for United's visit.
Against English teams, they have won only one of their last six
encounters, which was a 3-2 home win over Tottenham in the first leg of a
qualifier for the 2010-11 tournament.
Their last meeting with a Premier League team was in February 2015,
when they lost 4-1 to Everton in the last 32 of the Europa League.
Romelu Lukaku, the man likely to lead the line for United on Wednesday,
scored a hat-trick for the visitors that day.
Honours: Swiss Super League titles 12 (most recent 2018, Swiss cup winners 6 (most recent 1987), Swiss League Cup 1976, Coppa dele Alpi (now defunct) 1974.
Last time: FC Schaffhausen 2-3 Young Boys (Swiss Cup second round).
