The UEFA Youth League will be back on the pitch on Saturday, as the clubs are expected to take the field at 3pm BST.
The Europa League will return on Saturday at 2.45pm BST, with both the Group Stage and the Quarter Finals to be played on the same day.
All teams will be competing in the same Group Stage for the first time since the 2013-14 campaign, with the group stage winners receiving their respective domestic cup competitions.
The teams will then take part in the Group B play-off, which will be played as a knockout round, with a place in the knockout round guaranteed to each team.
As for the semi-finals, the sides will play a group-stage match on Tuesday, Wednesday and Friday, with three more matches being played at home.
The top two from each group will advance to the quarter finals, where they will meet in a second-round game to determine the Champions League place.
The winners of the group will play the quarter-finalists on Sunday, which is also a UEFA Youth Club Cup final, with their best-placed team being seeded into the group stages.
The Champions League will not be on offer for the Europa League, however, as UEFA has decided to make the event more lucrative, with teams getting a maximum of €100,000 per match.
