Bringing on Murray? Another issue altogether - doesn't support your argument in any way.Yeah lets go from 2 forwards to 1 to 'boost the attack'. Great move that was. Why even bother bringing on Murray!
Lets just agree to disagree, because there's no way I can see that substituion as being a move by Potter which gave us more attacking intent.
Two forwards are not a lot of use when the attacking midfield has just stop working - but you're clearly not going to accept that, so we move on.
