UEFA are reportedly considering making huge changes to the Champions League format that would see the semi-finals and final played over the course of a week in one city.
European football's premier club competition was forced to hold matches from the quarter-finals onwards in Portuguese capital Lisbon last season because of the challenges presented by the Covid-19 pandemic.
Games were played as single-match knockout ties at neutral venues in Lisbon with Bayern Munich eventually coming out on top against Paris Saint-Germain in the final.
The new format proved to be a hit with huge global TV audiences and the single-match knockout system giving ties an extra dramatic element.
According to The New York Times, UEFA are now set to unveil a plan to change the format to something similar before this weekend's Champions League final between Chelsea and Manchester City in Porto.
It will be called the 'champions week' and will have two semi-finals and the final played in one city in the same week. The final would still be held in its traditional Saturday night slot.
The plan will also include a schedule of concerts, games and other events to keep supporters entertained over the course of the week.
It is claimed the plan is under 'serious consideration' but UEFA are yet to put out an official plan because clubs have still not been brought into the discussions.
UEFA are said to have wanted to copy the NFL's Super Bowl concept, where there is a whole week of build-up and events before the match on a Sunday.
However, concerns from officials that huge TV revenue could be lost by missing out on two semi-final matches have prevented change.
But UEFA now believe the TV audience that would gather to watch a one-off game could lessen the financial impact of getting rid of a second leg.
It is thought the plan would be welcomed by Europe's elite clubs, who desperately want to cut back the amount of games their players are having to play.
Speaking about the mini-tournament format at last year's version in Lisbon, UEFA president Aleksander Ceferin said: '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.'
Any changes would not come into effect until at least 2024, when the new Champions League format begins.
Amid the backdrop of the doomed European Super League last month, UEFA pushed through enormous changes to the Champions League format from 2024.
The shake-up means the total number of teams has risen from 32 to 36 and the traditional group stage format will be abolished.
In its place a single league stage, which includes all 36 participating teams, will be devised which would see every team guaranteed 10 'league stage' matches.
Five of those matches will be at home and the other five will be away from home.
The top eight sides from that 'league stage' format will progress to the knockout stage automatically.
Those remaining sides running from ninth to 24th would then enter two-legged eliminators to determine the other eight teams into the last-16.
The football world was shocked last month after 12 clubs - including the Premier League's Big Six - signed up for the breakaway Super League, which threatened the future of UEFA's elite competitions and the viability of domestic leagues.
In a chaotic 48 hours amid mass protests from across Europe from fans, media and even politicians, the plans came to a shuddering halt with teams withdrawing one by one.
However, Barca, Real Madrid and Juventus have still not renounced their involvement with UEFA considering imposing bans from their competitions on those three clubs.
