The Argentina captain featured in the scratchy 1-0 win.
Mascherano said: â€œIt was a difficult game because Zaragoza put a lot of men back in defence. In the end, we went on and stretched our lead at the top ahead of Sundayâ€™s game, now we can think ahead to Tuesday when we have a very important match.
â€œThe boss decided to rest some players and it worked out okay with the win. Now, there will be players who are fresher on Tuesday."
