Soccer: Liverpool are our biggest title challengers, says Guardiola

(Reuters) - Manchester City manager Pep Guardiola said Liverpool are their "biggest challengers" for the Premier League title despite the Merseyside team trailing his side by 13 points ahead of Sunday's game at Anfield.

City, who have qualified for the last 16 of the Champions League, are second in the league table on 23 points after nine games, one point behind leaders Arsenal.

Liverpool have won only two of their eight league games and are 10th, but Guardiola said his opinion about them has not been changed by their league position.

"I know the quality they have, they know the quality we have. If this was with three games left, I would say they could not catch top of the league but, with so long left plus a World Cup, anything can happen," Guardiola told reporters on Friday.

"It's always difficult in the years since we have arrived here together, it will be a tough game and I don't expect anything else.

"The game will be dictated on the pitch, not by the table, because we are in front of them or behind, not because of those kind of things."

City have been one of the most consistent teams in world football this season, with the team yet to lose a game in any competition.

"This is our biggest achievement as a team," Guardiola said.

"Everything can change. A few months ago Liverpool were competing for a prestigious situation in English football, four titles, they had more shots, possession, everything in the final and they lost.

"This is the same team, same manager, things can happen. It's part of the nature of the competition. I don't look at good moments or bad moments I analyse as a team always expecting the best of them."
