The former Real Madrid junior was watched by United scouts last month.
Asked about the interest, Sarabia told Fichajes.net: "My agent and I never talk about this during the season because I think it is a way to unbalance a player and distract them from their work.
"What I have to do is stay focused on the goal, which is to save the team.
"Clearly, if the interest is real, I'm proud that such a great club notices you, but now I have to be focused here and give the maximum for the club of Getafe."
On playing in the Premier League, Sarabia, a favourite of Real Madrid legend Alfredo di Stefano, added: "It is a very attractive league. It's very physical but in recent years we have seen several Spanish teams have taken that path. And why not try it some day?
"Although I have to focus on here today. In the future we'll see."
