Brady believes Cobblers in better shape for Wigan challenge this time around
The Latics claimed a 2-1 success over Town on the second Saturday of the season, with Sam Hoskins' first-half opener being cancelled out by two goals in the space of seven second-half minutes to hand the home side all three points.
The Cobblers played well and had the chances to win, but Brady believes he and his players will be a much stronger proposition for Shaun Maloney's team this weekend.
"We had some constraints back then didn't we?," said Brady.

"But we are in a different position at the moment, and we are really looking forward to the match on Saturday."
Wigan are 18th in the Sky Bet League One table, as they strive to overcome the eight-point deduction dished out to them in the summer over financial irregularities.
They are four points above the drop zone, but Brady knows that is a false position as without that deduction, they would be one point and one place below the Cobblers.

"They can change shape, they can play with a back four, a back three, and they do that through the game as well.
"It is going to be a totally different challenge on Saturday."
Wigan are going into Saturday's game off the back of their 2-0 FA Cup third round defeat at the hands of Manchester United on Monday night, and Brady was impressed with what he saw in that encounter.

"They are a good side as we know. We played them earlier in the season and it was a tough battle up there, and they have got some very good players for the level, and a very good squad for the level.
"But we are acquitting ourselves well too, and it should be a good game."
The Cobblers will have Lee Burge back in goal after injury on Saturday, with Max Thompson having returned to Newcastle United at the end of his loan spell.

Top-scorer Hoskins is a doubt to take on Wigan as he tries to recover from a groin strain, while Sam Sherring, who hasn't played since Boxing Day, will definitely miss out.
