Simon Church netted the winner for the Royals with two minutes to go after both sides had been reduced to 10 men when Town's Luke Hyam and Reading's Matt Mills saw red for two bookings apiece.
Keane said: "I`m not sure we deserved to win. Anyone who knows anything about football knows that if you don't put the ball in the back of the net then trust me, you are going nowhere fast.
"We didn't play badly but if you don't get goals you will not win. Our leading scorer got eight goals last season and if that happens again we are in trouble.
"I do think our strikers need a little more to work from as well. It's a team game and we all have to do better.
"The back four have done well because Reading are good going forward. We now have a couple of suspensions but don't worry, we can get 11 out for the next game."
