European international club events with new system ending

Both the European Cups (leagues) are way behind the schedule, and just to quicker the proceedings, the confederation has found out a new solution of how to end and salvage the current 2019-20 season. Instead of one final duel played in a single town at Istanbul (Turkey) and Gdansk (Poland) five days ago, it was confirmed a new system called 'Final 8'.
Four matches still have to complete the round of 16 scheduled for 07 and 08 August. Those four overall winners together with the four already qualified for last 8 phase in the Champions league are going to compete at the Portuguese capital Lisbon from 12 until 23 August: everything has to start with quarterfinal games who will be played of 12 until 15, 18 and 19 are semifinal duels, while the last is going to be staged on 23. Couple of stadia is going to welcome the best eight clubs: Estadio do sport Lisboa e Benfica (formerly known as Estadio da luz) and Estadio Jose Alvalade.
Germany in a similar way is going to host the most interesting tournament out of the two. Europa league is going to be played in four cities: Cologne, Duisburg, Dusseldorf and Gelsenkirchen of 10 as far as 21 August. However, the round of 16 matches are going to begin on 05 and 06 August with the second 90 minutes.
Draws for each of the penultimate two phases (quarterfinals and semifinals) will occur on 10 July. After these two stages are finished another draw is going to be made, just to see which team will 'pose as a host' in the last game.
