Europe’s football governing body were forced to get creative this summer after the coronavirus pandemic disrupted the footballing calendar around the world.
After completing the round of 16 ties, UEFA decided to relocate the tournament to Portugal, where the remaining stages of the competition would be completed in single-legged ties to decide the winner.
There have been some shocks along the way as powerhouses like Atletico Madrid and Manchester City have been knocked out by minnows RB Leipzig and Olympique Lyon respectively.
The competition has reached its final game, where Paris Saint Germain and Bayern Munich will square off in Lisbon later on Sunday.
Ceferin says he is a fan of the current format but is unsure whether UEFA will consider changing it in future.
“We were forced to do it but in the end we see that we found out something new. So we will think about it in the future for sure,” Ceferin told Reuters in an interview.
“[There has been] not so much tactics. If it is one match, if one team scores then the other has to score as soon as possible. If it is two-legged system then there is still time to win the next match.
“I have to say that this system of one match seems more interesting to me than the other system with two-legged matches, but again it's much too early to say anything about it, let's see.
“Because the Champions League was interesting before – it's interesting now [too], it's quite a nice experience if you have to think about changing something that works well anyway. So, it's not the pressure that something doesn't work and we have to change it, we don't have to change anything, but we've got some new ideas now.”
