This time just last week Manchester City were on the receiving end of a 4-2 trouncing at the hands of German side Stuttgart - far from the ideal way to conclude pre-season before the opening of the Premier League.
Fast forward seven days and City fans have a much brighter perception of their side after a dominant victory over West Brom on the opening day.
The difference in performance was so vast the side was almost unrecognisable.

And while the victory might have only come against mid-table side West Brom, the signs were certainly there that Manuel Pellegrini's men will be up there the title challengers this season.
Not just because they beat West Brom so convincingly away from home, but also because, for a brief moment, there was a glimmer of the dominant side that romped to the 2013/2014 title.
The key to their victory was none other than City's big Ivorian danger man, Yaya Toure. Whenever Toure hits serious form, so do the Citizens.
You only have to look back to last season to see evidence of how big an impact the midfield powerhouse has on his side. City were level on points with Chelsea at Christmas but soon slumped in form when the 32-year-old midfielder departed for the African Cup of Nations.
Whilst the season before that, Yaya Toure was scintillating, constantly leading the charge for the Blues and leading his side to their second Premier League title in three years.
Sergio Aguero's fitness, Vincent Kompany's form, and David Silva's consistency have all played a similar role in City's title bids, but if past seasons have shown us anything, it's that Toure, above all else, will have to be at the top of his game if City are to build a sustained bid for the title.
