Northampton Town manager Aidy Boothroyd has urged his side to build on their first-half performances.
He told BBC Radio Northampton: "First half, I would imagine that we're the best team in the league since December.
"In the second half, that's when we've got to lock down the hatches and have a little more concentration."
Boothroyd added: "The fact that we went 1-0 and 2-1 up [against Southend] suggests that we're capable of beating teams."
Saturday's defeat by Southend left the Cobblers, who face 20th-placed Barnet in their next fixture, bottom of League Two.
"They're all crucial. We've got games left to make sure we get out of the position we're in and I'm very confident that we will," said Boothroyd.
"The supporters are seeing a team that's always in a game and having a go.
"We're a club that's tidying up and making sure we're always fighting for our lives."
Meanwhile, Boothroyd has urged his young loan players to put in good performances for the Cobblers if they are to catch the eye at their parent clubs.
West Bromwich Albion striker Saido Berahino has scored six goals and will remain at Sixfields until at least February.
"Saido is a good player but he's not the end product yet, and that's why he's here, that's why Blair Adams is here and why Akwasi Asante is here," added the Northampton boss.
"They're here to learn the trade and they're performing well. Saido is getting better and better and he's got a real chance of playing at his own club eventually.
"But he needs another half a season here to prove himself at this level so he can move on and do better."
