Despite his previous assertions that his much vaunted trio of Cristiano Ronaldo, Gareth Bale and Karim Benzema is "untouchable", the Frenchman also discovered last season that his alternatives aren't bad either.
Thus Zidane must decide on whether the 'BBC' will continue to be the undisputed forward line for Real, or whether the likes of Alvaro Morata, Isco, James and Marco Asensio deserve more game time.
All of those players impressed last season when they were given the chance to play, with Morata outscoring Benzema despite playing second fiddle for much of the campaign.
Another memeber of the 'BBC' Gareth Bale was statistically Real's least successful creative player last season as we reported recently. The Welshman endured a frustrating campaign and given his apparent susceptibility to injury can he really be relied on over the course of a full campaign?
With question marks over Cristiano Ronaldo's future, Zidane may be forced into a change of forward line, but if this is the case, does he already have players in his squad that can step up?
