"Liverpool are a really great team, everyone would love to play there," he replied.
"They won the Premier League this year and the Champions League last year. But there are other great teams in the English league.
"Frankly, I have yet to make a choice. If I am to leave, I just hope it is for a good team. At the moment, it is just guesswork."
But Sarr also made it clear he would respect the remainder of his Watford contract if the club refused to sell, despite the Hornets being relegated to the Championship.
"I still have years left on my contract with Watford; another four years," he said.
"If Watford want me to stay, I'll play in the Championship. A departure depends on them as well as me. This is normal.
"Personally, our relegation hurt me a lot. I didn't think we would come to this. I told myself that we had to do everything not to go down to the Championship.
"We did our best to prevent this situation but you have to know our relegation wasn't the result of our performances at the end of the season.
"During the season, we lost easy matches that we had to win. We often failed at home.
"For example, against Everton we were leading 2-0 and ended up drawing 2-2. It wasn't because of the matches against Arsenal, West Ham or Southampton [at the end of the season], but long before that."
