Given that we won 3 from the last 4 PL seasons, it's not a particularly important stat. Obviously, it's not easy to score first against City and the consequences for the league campaign are not big when it happens. Also, this team has won highly important games this year or has avoided losses this season after conceding first: Dortmund, Paris, Liverpool.
To think that Palace had as beaten as soon as they scored is to exaggerate. If we can score twice at Anfield after being down twice, we can do it at the Etihad against any team in the world, great, good or average.
I'd like to see the real stats for our games at the Etihad when we concede first. I'm sure they are not that bad (1:10) anyway.
