Scunthorpe United manager Russ Wilcox believes his side's 0-0 draw with AFC Wimbledon was a reality check.
The result stretched their unbeaten run to 10 games under Wilcox but the Sky Bet League 2 leaders found themselves frustrated for long spells.
They could not find a way past goalkeeper Ross Worner as he produced a man of the match performance for the visitors with three good saves to deny Scunthorpe's leading marksman Sam Winnall.
"Sometimes you have got to give credit to the opposition. Wimbledon made life difficult for us," said Wilcox.
"Whether this point will be a good one for us or not, we will see at the end of the season.
"But this was maybe a bit of a reality check for for us. We have been on a great run and, although it has not come to an end, it does feel a bit like that.
"Now we are top of the table, we know that teams are going to make things difficult for us, getting plenty of men back behind the ball.
"We have got to be creative enough and good enough to overcome that.
"I thought we lacked intensity to our play in the first half. We increased the intensity in the second half and got the crowd behind us, but we could not find the creativity to break them down.
"We were not good enough in the final third.
"But we have not to let ourselves get down. There were still many positives for us to take out of the game.
"We care still two points clear at the top of the table and have got a squad now where there is going to be plenty of competition for places."
AFC Wimbledon answered manager Neal Ardley's call for a response to last week's home defeat against Torquay with a well organised and battling performance.
They also did it despite losing key defender Andy Frampton with a dislocated shoulder after only 10 minutes.
"Coming here to play the league leaders, we knew we had to have a togetherness about us," said Ardley.
"I know Ross Worner has pulled off a couple of good saves to help us, but we have worked really hard as a team to earn this point.
"If I was nit-picking I would say we lacked a bit of quality at times when we got the ball into the attacking area.
"But overall I have got to be pleased with the reaction after last Saturday's defeat at home to Torquay.
"We have struggled at home against teams near the bottom and have got to make sure we work hard to put that right.
"We have got to make sure that the point we have worked so hard for here at Scunthorpe is made into an even better one by taking four points from out next two home games. That is really, really important for us now."
