-*Strength across the midfield*
The strength of Zidane's midfield is perhaps his biggest asset; Casemiro, Toni Kroos, and Luka Modric are backed up by Isco, Mateo Kovacic et al. This has provided balance, flair, and a seamless team ethic. While Luis Enrique can call upon the exquisite Andres Iniesta, providing he's fit, there has been a marked drop in form from Ivan Rakitic whilst Gomes, Denis Suarez, and Rafinha all lack the consistency or raw ability to fit the bill.
-*The rise of ter Stegen*
One are the Blaugrana can be happy with is the goalkeeper. Even in the defeat to PSG, Marc-Andre ter Stegen stood head and shoulders above the rest, making clear that he is the undisputed custodian at the Camp Nou. Meanwhile, Keylor Navas has been unable to do the same, sparking rumours that Real are in the market for a big name signing to replace him this summer.
-*MSN vs. BBC*
For all the talk of Madrid's BBC vs. Barcelona's MSN, Los Blancos haven't been able to field their preferred front-three in three months. This is typical of the more fluid approach to selection that Zidane has revelled in whereas Luis Enrique has persisted with his attack line and with imperfect results.
