Ahead of another Champions League salvage mission there is no room for error for Barcelona as they try to chase down Real Madrid at the top of La Liga.
Given that Zidane is expected to heavily rotate his side, Los Blancos might not be at their fluent best but they have real quality on their bench and their fringe players should be more than able to pick up 3 points on Saturday night.
The midfielder first responded to Duje Cop's 14th-minute breakthrough before adding his second in the game's dying minutes, with Alvaro Morata cancelling out Mikel Vesga's headed effort earlier in the second half.
Just when it looked like Sporting would hold on for a point, Isco drilled a low shot into the bottom left corner from the edge of the penalty area to keep Real in charge at the top of the table, with the Clasico to come next weekend.
"He's fine, very up for it and few players are going to manage to score 100 goals in European competitions".

Isco hinted that he could sign a contract extension with Real Madrid after his two-goal heroics against Sporting Gijon.
Madrid, still have seven games in hand, one more than their their rivals, Barcelona, Atletico and Sevilla.
Isco hailed his side's DNA to fight till the end, but accepted the European champions made life hard for themselves against relegation-threatened Sporting.

The second half couldn't have gotten off to a worse start and that was despite Real Madrid coming close to getting their noses in front after James' 48th-minute free-kick was met by Nacho and the ball danced along the goal-line. This is the best run by any LaLiga team. Boss Luis Enrique therefore has a delicate balance to find between resting some of his star names ahead of another Champions League rescue mission in midweek and still having enough to see off a Sociedad side battling for a place in the Europa League. Madrid must scribble out a win, by hook or by crook at this stage of this season, no matter how they play.
Real will be defending a 2-1 lead from the first leg of the quarter-final, which the Polish hitman missed with the shoulder injury that also kept him out of the German side's 0-0 draw at Bayer Leverkusen in the Bundesliga on Saturday. "I don't know why people are surprised when I say I want to play more".
