Bayer Leverkusen get their UEFA Champions League campaign underway against Feyenoord on Thursday and come into this year's new-look edition as German titleholders. Xabi Alonso's side dislodged Bayern Munchen from the summit and will open their quest against last year's Eredivisie runners-up at De Kuip in one of the early kick-offs.

Barcelona opened their Champions League campaign with a 2-1 defeat in Monaco after playing most of the match with 10 men following an early red card for defender Eric Garcia. Hansi Flick has made an impressive start at Barcelona after taking over in May, winning their opening five LaLiga fixtures to sit top of the table.
