I agree he puts too much emphasis on it, but we've also scored from inswinging set pieces against Tottenham, Reading and Birmingham this season. I'd be surprised if we scored that many from set pieces all of last season. Also, iirc, wasn't Owen's goal against Everton from an outswinging set piece from Emre?
Only because Geremi and Milner had gone off. Had either of them still been on the field, Emre would not have taken the kick.
Yeah it's working to an extent but it's almost working too often - that's the only type of goal we're scoring and not enough! You can't base your game around set pieces. You can be strong at them, the best sides still are, but football matches by and large are won and lost in open play. They're good at that too, we're not.
