Liverpool will begin their defence of the league title this weekend when they welcome newly-promoted Leeds United to Anfield.
Jurgen Klopp’s men won the top flight for the first time in three decades last season, finishing 18 points clear of nearest challengers Manchester City.
Former world number one Wozniacki, who retired from tennis earlier this year, is a lifelong Liverpool fan and she has backed the Merseyside club to keep hold of the trophy this season.
"I was so thrilled when they won the title," said Wozniacki on Sky Sports' Check-In with Hannah Wilkes.
"We've been waiting a long time for this and I think all us Liverpool supporters during the year were keeping everything crossed that this was going to be the year and we all at one point had to shake our heads when the pandemic put a stop to the whole world.
"I felt like the timing of that with Liverpool could only happen to us but at the same time, I'm so glad that they finished the season. They were the best team last year, they won the Champions League the year before, and I'm so happy and proud of the guys."
"I definitely think they have a team to win it again this year," the Dane added. "I have all my gear, I have everything, so I'll be watching every game."
