I'll tell you when the Kopites got so confident of winning the title: the moment that Coote video dropped.
They knew no ref would ever hand them anything other than bent decisions all season long. Even more than any other season. That sealed the deal. And they were right.
They'll win the title this season because of that.
Last night was a defeat for City or Arsenal if they'd done the same: certain red card for any player of theirs throwing a shoulder into an opponents face and decking them with it ending treatment; certain pen for the outstretched leg in the box.
Unfortunately this is done. It's been decided. The PL and PGMOL wont allow any other outcome. You could have A galactico Real Madrid in a race with Liverpool for this title and they'd still lose the league to them by 5/6 points.
