The Spanish creator has not made a consistent impact on the team since arriving from European champions Bayern Munich in the summer.
He has also struggled with illness and injury this term, and the 30-year-old has said he has endured a tough transition into English football.
"I would say it's a much faster style of football than in other leagues so a lot of it has been about finding the rhythm," he said about the Premier League, per the Liverpool Echo.
"But in terms of quality, tactics and strategy it's the same as the others.
"It's more a question of adapting to your new life outside of football rather than professionally.
"I'd come off the back of a successful season with Bayern, and so I arrived here in good form and feeling fit and was warmly welcomed with the good wishes of my team-mates and all the fans too.
"Unfortunately, in the first week I go COVID, and then as soon as I'd got over that, I sustained the injury in my first game back against Everton.
"So you could say it was a tough start for me, and now I'm continuing to adapt and settle in. But the club have given me every possible means for that process to happen as quickly as possible."
He added: "Moving between countries is something I've done a lot throughout my life.
"We would move frequently when we were young because of my father's career.
"At the same time, you arrive in a new country that you're unfamiliar with and now with the COVID-19 situation you don't really get to know your new home.
"Our lives are 100% football at the moment - home, training, home, training - so you could be anywhere in the world."
