Manchester United continue their Europa League venture against FC Copenhagen in the quarter-final tie, with the final rounds of the tournament being played in Germany.
Following the coronavirus pandemic that disrupted global sport, the quarter-finals, semi-finals and finals will be played as single-tie matches in a neutral venue.
For the Europa League, Germany is the host and United will spend the remainder of their season on the continent - as they are not allowed to return to the UK until their involvement in the competition is at a close.
It is a far different format than fans have become accustomed to, so we have gathered all the ins-and-outs that you need to know.
Is there extra-time and penalties?
Yes. Any match that finishes level after 90 minutes will immediately advance to extra-time and penalties, if necessary, with each match being decided 'on the night'.
This means there is no aggregate scores or away-goals rule, with the set-up being described as 'no second chances' - as a single tie will decide the outcome of each round.
It is comparable to the international tournaments that are played, with the tournament taking centre-stage after the European Championship was postponed.
How many substitutes are allowed?
Each team is allowed to make five substitutions over the course of the match, with the number rising from the usual amount of three due to the rigours of the extended season.
However, to limit the number of stoppages to the match, each team will only be allowed to make changes at three points during the course of the match.
If the game advances to extra-time, each team will be allowed to make an additional substitution.
