A little more than a week ago, the Premier League title was being seen by many as a one-horse race.
Champions Manchester City had looked imperious once more with six wins out of six, leading former Blackburn Rovers striker Chris Sutton to tell BBC Radio 5 Live, "let's be honest, we are all expecting Man City to run away with the title again".
He was not the only one thinking this way, but what a difference a week makes. Defeat in the Carabao Cup by Newcastle and a first loss in the league to Wolverhampton Wanderers has left Pep Guardiola's men looking a little vulnerable.
