AFC Wimbledon boss Neal Ardley admits it will probably only take one more win for his side to secure their League Two status, but he is taking nothing for granted after conceding a late winner at home to Barnet.
Substitute Keanu Marsh-Brown struck five minutes from time on his debut to secure a 1-0 win for the Bees, leaving the two sides level on 48 points and three clear of York in 23rd.
After seeing the Dons' unbeaten home record in 2013 come to an end, Ardley urged his team not to waste their good work.
He said: "We didn't win but we can't moan about it. Perhaps if we got our set pieces right and we had a bit more quality we could've been one up at that point but we didn't.
"I'd be surprised if 51 points isn't enough but it's not the case of one more win and shut up shop, it's the case of one more win and then go for the second. It just means the pressure is still there. We've been mentally strong, we've dealt with the pressure for the past three months and we can't let the good work go to waste.
"We'll rally the troops, it's my job to pick them up and take them forward. This is the league this year, it's one of those leagues. League Two will be a battle till the end.
"I didn't think they were a threat. That's my opinion and I might be wrong. I thought there was only going to be one team to get the win in the second half. It's really disappointing when a slip-up costs you."
It was a vital win for the Bees, who are now unbeaten in four and have not conceded a goal since mid-March.
"The defence was definitely put to the test because the pitch was horrible and they gave us a good fight, they were solid," said player-manager Edgar Davids. "Keanu Marsh-Brown is a young talent, he did very well and if you practise well then you play well. It is important when you come off the bench that you show the coach that you are worth playing for the first team and he did.
"I'm delighted for the four clean sheets but I am all about progress. The last couple of games we didn't play that well so we definitely have to work on certain aspects."
