Jim Bentley is hoping the town will come out and support his Morecambe side on their return to the Globe Arena on Saturday.
Wins on the road against Yeovil and Newport County mean The Shrimps, fifth in League 2, have won four straight ahead of hosting Northampton.
Bentley said: “It’s been a good week or two for us.
“We’re doing well in the league, scoring goals and winning games, and now we’re back in front of our home fans and hopefully the local public will get right behind us and come out and back us in what is a big game for us.
“We’re fifth, three points from top of the table, we’re the second leading goalscorers in the league, we’ve got some exciting players, things are going well and we need the town to get behind us.
“We can’t really do much more.
“We’re playing one of the fancied sides in the league and it should be a big game.”
Bentley is ready for a stiff test against a constantly improving Cobblers side.
After taking over in January 2014 boss Chris Wilder kept Northampton in the Football League before guiding them to 12th in League 2 last season.
This time around, boasting a squad including the likes of former Port Vale and Chesterfield striker Marc RichardS and former Preston men Joel Byrom and David Buchanan, Wilder will be looking to take his side into the play-off places.
Bentley said: “Northampton for me are one of the better sides in the league with the front four they’ve got and the back up.
“Marc Richards is arguably one of the best centre forwards in the division.
“They’ve got good firepower and options.
“They have been a little bit up and down with results and doing the work on them it looks like they’ve struggled at central defence at right back.
“But last week they went and signed (Peterborough’s) Shaun Brisley and Darnell Furlong from QPR on loan and that’s tightened them up.
“They played extremely well when they won 1-0 on Saturday (against Oxford).
“They’re a big club at this level with a manager who knows it (the level) well.
“Like us they’ve got goals throughout the team so it’ll be a tough test for us.
“But I’m sure Chris Wilder is saying exactly the same to his players.”
