Pep Guardiola sent Mikel Arteta a message about bottle at Wembley.
If he’d sent a warning - a message in a bottle, if you like - ahead of this week’s Judgement Day at the Etihad, it would have been spelled out in large letters. And it would have read as follows: That Manchester City are primed, ready and waiting - as they showed just how to handle pressure at Wembley.
This scoreline was emphatic. It didn’t need to be. At the final whistle, it just needed to be in favour of those wearing sky blue. But if the treble was to be kept alive, this was a hurdle they needed to overcome.
