LONDON (AP) — What will it take to win the English Premier League with six games remaining? That’s easy — perfection.

Manchester City, Arsenal and Liverpool — all eliminated from their European competitions this week — are locked in a tight battle for the title.

Defending champion City leads both rivals by two points but with Pep Guardiola’s team playing an FA Cup semifinal against Chelsea on Saturday, Arsenal and Liverpool can gain ground.

“If you want to be champion in the Premier League, you have to be close to perfection,” Liverpool manager Jurgen Klopp said on Friday ahead of a visit to Fulham on Sunday.

“Anything other than perfect, you have to deal with the setbacks in the best possible way. That’s what we are now doing. We had a setback week,” he said. “Now we have to start turning it around.”

Arsenal, too.

Mikel Arteta’s team gets first crack at retaking the league lead when it visits Wolverhampton on Saturday.
