"It's terrible. I'm the sort of player who misses two games a season at most through injury, so it's a very strange situation for me. I hate it when I'm not playing games," the Spaniard told the club's official website.
"I'm certainly not used to it. Now I know how the fans feel when they're watching us play. You see so much from the stands that you can't appreciate when you're involved in the match.
"I suffered when we were going through difficult periods against Everton and Besiktas, so yes, I'd much rather be out there than in the stands."
