Pep Guardiola, the manager of Manchester City, has confessed that Jurgen Klopp, the manager of Liverpool, is his greatest professional opponent.

On Sunday, both managers will square off in what has been dubbed a Premier League title clash.

Guardiola's side has fought the Reds for domestic dominance on multiple occasions throughout his rule, and the race is once again going down to the wire this season.

Going into the vital match at the Etihad Stadium, City, the reigning champions, are only one point ahead of Liverpool, who are in second place going into the vital match.

In the previous five years, they've been the most formidable foe. They've been fantastic contenders, with strong performances. As a manager, Jurgen (Klopp) has been the most formidable opponent I've ever faced.

“I will remember my period here. When I’m retired and watching and playing golf, I’ll remember my biggest rival was Liverpool, for sure,” Guardiola told reporters.
