To answer my own question, it is the point of contact that counts, so wrong decision.
I don't buy this 'foul continues into the box' argument, if the foul is committed outside the box it must surely stop there and then.
Anyway, Danny Welbeck's last week was never a penalty either, so these...
Genuine question - for a foul, is it the point of contact that counts? or is it the position of the attacking player, i.e. the same criteria that is used for an offside. If its the latter, it is a penalty as t-shirt line on the arm is in the area.
I'm sure for the Lalllana/Kane one a while...
