Daniel Candeias’ attack gave the Ibrox side a 1-0 win over Hamilton to maneuver them to the table’s top.
“I am glad we’ve won, but I am content with a fresh sheet, but we need to improve,” he told Rangers TV.
“With certain facets of the game I’m [pleased]. Without the ball now we were really good – however whenever we got the ball in good are as we did not have a killer instinct.”
Candeias got Rangers off to a perfect start with an objective in just three minutes, and Gerrard maintained his side needs to have had the match won”after five minutes”.
“[We’re missing] that bit of quality, someone who is going to step up and kill the match,” he told Rangers TV after his team moved before Kilmarnock on goal difference.
“We should have won this match after five minutes today, we should have already been three or two nil up.
“We’d 21 corners now. I am guessing but we had 30 crosses into the carton. We’re playing up to point, but some body is going to want to go and score a goal or wish assist and to really go a goal to kill Hamilton.
“If it extends to 2-0 I will take James Tavernier off the pitch because he has played every moment, and I will break people for the more important games coming up.
“However, I did not have this luxury. Hence that the plan I had in my own head sought from the window because we did not have a killer instinct.”
When asked about his side returning to the top of the team, he replied:”Not interested at the top of the league. We were top of the team against Hearts and as a team we’ve suffered for eight days.
“The players have done a great deal of things today, but now being a Rangers player includes responsibility and pressure and you also need to step up at that final area of the pitch.”
