#4 Hit: Sergi Roberto
Often an unsung hero in a Barca side packed with world-class ability, Sergi played a pivotal role in helping the hosts regain their composure after a worrying Real flurry of attacks.
Dependable as usual at right-back, he really excelled when Valverde opted for a formation switch of his own, allowing the 24-year-old the opportunity to venture forward into central midfield, his preferred role. His intelligent movement, energy and efficiency off-the-ball meant Real were playing catch-up in an attempt to track his runs.
Crucially, it was his deft pass into Suarez who headed beyond Courtois into the bottom corner to regain their comfortable cushion and see the game's momentum switch once more. He was unlucky to have only created a solitary assist, having latched onto a deep cross and flicking it back into Luis' path - only for the Uruguayan to volley an effort which cannoned back off the far post.
It was a memorable win and Barca collectively were brilliant, but Roberto's display, in particular, stands out as he rarely gets the same level of praise as his midfield counterparts.
