#2 Team selection, tactics and formation
After an underwhelming end to a torrid domestic campaign on Sunday, Zidane stated that he had all the 24 players available for the big night and summarised his feelings about it by blatantly moaning that he was 'fu**** up'.
That's what the problem of plenty does to you more often than not. Klopp, on the contrary, might go with the traditional 4-3-3 with Wijnaldum playing behind the front three and Milner playing with Henderson in the central midfield.
Virgil Van Dijk ought to start as central defender along with Dejan Lovren while Alexander Arnold may start with Robertson as the full-backs. Bale looks set to regain his place in the starting XI given the breathtaking form he is in.
Another thought doing the rounds is that we might get to see the famed trio of 'BBC' back again which seems quite logical as well, but I personally feel that Benzema will have to make way for Isco given the scanty amount of game time he has had in the past few fixtures.
Also, it will be quite interesting to see will be how Klopp manages to make use of his substitutions if the game goes into extra time. That, although seems unlikely given the number of goals that will be plundered within regulation time.
Contrarily, Zidane has made a living out of his timely and tactical substitutions who have time again bailed his team out, with Marco-wonderboy-Asensio and Lucas Vazquez providing the fresh legs and width required on the pitch late in the game.
As far as tactics are concerned, the "geggenpressing" style of Klopp has stuffed the momentum out of many a side in Europe and against Madrid, the Reds will surely look to harass the Madrid players on the ball.
Casemiro, of all Madrid players, always seems a bit uncomfortable on the ball and I won't be surprised if he's touted as the trigger point for Klopp's hounding boys.
A riveting off-pitch encounter awaits us, innit?
