Sorry but that is simply not true
Possession is 50% of the game - any manager who's worth his socks would tell you that. Controlling the game you control the tempo, your opponent is always chasing, tiring, becoming frustrated and inevitably leading to mistakes on their part.
Look at teams like Barcelona - quite possibly the most vivid example in recent years. Their 5 second rule has become painfully efficient and yet so simple.
Yes, we might be a little sloppy at this early stages of 'implementation' but in 6 months time (estimate) it could be a ruthless, well-oiled machine. We scored 3 goals last night and dominated the game - so to say all this possession didn't lead to any chances is vastly off the mark.
