Hahahaha.

You need to stop listening to the shit punditry going around at the moment that we're going to be vulnerable in defence.
Guardiola has managed 7 seasons of football, he's had the best defensive record in every season he's ever played - including the 2 seasons in La Liga against coaches like Mourinho and Simeone who are known for their teams brilliant defences. In 11/12 Barcelona conceded 50% fewer goals than Mourinho's team.
And you think we won't be the "solid unit" we were under Pellegirini - that actually made me laugh out loud.
Guardiola's game plan, the way he sets up, the whole positional play system - it's all to do with structure, so that we are incredibly hard to score against. His much talked about "15 pass rule" is there so that when you lose the ball everyone is in position to defend effectively.
Take a minute to actually think of the goals we've conceded in the league. There's been 4 of them.
1 from a bullshit penalty. 2 from goalkeeper errors we can attribute to Bravo being late to arrive. 1 from Defoe.
The goalkeeping errors will go away. Bravo didn't win 2 Copa America's without being able to catch a cross. The bullshit opening day penalty won't happen again, and to be honest even Defoe's goal came in our first game when everyone looked confused about Pep wanted.
I would be absolutely amazed if we don't have the best or second best defence in the league this season, and there's absolutely no chance we ever concede 40+ goals like we did under pellegrini. It will probably be more like Mancini's best season - 29.
