Two sad facts about football.
1 - You cant win matches by not conceding goals unless you are scoring more than you concede.
2 - The casual supporter is more likely to pay money to see goals being scored as opposed to a decent defensive unit.
So Ernie has it right when he bangs on about needing a striker because even if you give away 3 soft goals in a match, you can still take all 3 points by scoring 4!
