Manchester City boss Pep Guardiola insists his team may not be good enough to win the title this season despite their success during the last campaign.

The Citizens remain 1.67 favourites to life the Premier League trophy after they cruised to glory last year under the Spaniard.

City set a number of records during the campaign, including most points, most wins, most goals and biggest winning margin.

Both Arsenal and Liverpool have spent big as they try to cut the gap, while Chelsea have appointed Maurizio Sarri to try and guide them to another trophy.

Manchester United and Tottenham were left frustrated in the transfer window but will still be expected to challenge and Guardiola admits his troops are not guaranteed to be successful, despite most media outlets claiming they will be the team to beat.

He told Sky Sports: “We were the best, definitely, no doubts about that, but we don’t play alone. We can do our job but the others can do their job too.

“We can do our job the same as last season but maybe Liverpool or United, Arsenal, Chelsea or Tottenham can do much better and they win.

“We can be excellent but the others can be excellent too. We cannot deny the other contenders. There was a gap last season but this season I don’t know.”

City take on Arsenal on Sunday and they are 1.80 favourites to win at the Emirates. Unai Emery’s side are 4.20 outsiders, while the draw is 3.80.
