Celtic will discover their Champions League Play-Off opponents on Monday, August 3, with a place in the league phase of Europe’s top competition now coming into sharp focus. The Hoops go into the play-off draw as a seeded side, although that offers no guarantee of a second leg under the lights at Celtic Park. Defeat in the play-off round would see them move directly into the Europa League league phase. The Squad DeadlineCeltic must submit their main 25-man Champions League squad by 10.59pm on Thursday, August 13. With the draw only days away and the squad submission deadline following shortly after, the next two weeks could shape not only Celtic’s Champions League campaign but also the final look of O’Neill’s squad heading into another demanding season.
