Because its last performance was the showcase, the one by which you can judge it. You can HOPE the next performance is better but you can't judge a team by what it hasn't done, only what it has. It's no good judging Spurs by the Everton or Burnley performances now because they're weeks ago, we can only judge Spurs by the City performance because it's the most recent. Teams can go from good one week to bad the next. Forwards can go from 20 yard screamers one week to missing sitters the next week and often a bad performance means the start of a winless run or a forward missing a sitter can be the start of a goal drought.And yet they still won and didn't concede a single attempt on goal.
Why?
Barca didn't score last night did they PNP? Could easily be the start of a bad run.
