Martin Allen called on his Barnet side not to get carried away after their 2-1 win over 10-man Woking on Saturday left them seven points clear in the Conference Premier with 13 games left.
In-form striker John Akinde gave Barnet the lead from the spot after 26 minutes with Cards defender Joe McNerney was sent off after bringing down the 25-goal frontman.
A comical own goal doubled the lead and secured a second successive victory for Allen's side as Joey Jones' back-pass eluded goalkeeper Jake Cole.
However, the Bees were made to sweat in the final 11 minutes after Yemi Odubade broke through the home defence and beat Graham Stack.
Woking poured forward and Josh Payne nearly broke Barnet hearts in stoppage time but his effort flashed over the bar as Barnet held on to take the points.
Allen said: “You can’t get carried away thinking you have got to do something different or carried away thinking you are really good. We have to keep our feet on the ground and keep doing what we have been doing.”
“When you are in this position you do just have to concentrate on what you are doing and having good habits, good standards around the training pitch, in the dressing room, being professional, looking after each other and just doing the job.”
Barnet travel to strugglers Wrexham on Saturday as they look to maintain their lead at the top.
