#5 The match itself
Real Madrid facing Manchester United is a reason in itself to watch the match. Two of the world's biggest teams facing off to lay down an early marker in Europe that they mean business is enough incentive to tune up for the game.
Further, United had a relatively easy route to their Europa League win but credit to them as one can only play who is in front of them. Thus, this match provides a better test as Mourinho prepares his side for a return to the Champions League.
On the other hand, Madrid won the double of La Liga and Champions League last season and have a settled core. However, key bench players Alvaro Morata, James Rodriguez and Danilo have left for shores anew with replacements yet to arrive.
Despite this, the likes of Karim Benzema, Bale, Ronaldo, Marcelo, Ramos and Luka Modric facing off against Pogba, Lukaku, Henrikh Mkhitaryan, Ander Herrera and de Gea is a mouth-watering prospect.
Thus, the clash of titans in its truest sense is the biggest reason for watching the UEFA Super Cup.
