Luis Enrique might have a lot of flaws as a coach, but failing to make rotations isn't one of them. The coach has an almost non-negotiable policy when it comes to resting key players, and this game was no different.
Enrique started an odd back-line for the evening that included Vidal and Mathieu on the flanks with Umtiti partnering Gerard Pique in central defence. In the absence of Sergio Busquets and Andres Iniesta, Andre Gomes and Arda Turan found spots on the starting XI along side Rafinha in midfield.
However, for the first time, Paco Alcacer would start a game alongside Messi and Neymar.
