Latics boss Lee Johnson is anticipating a tough clash when the Gills arrive at Boundary Park for Saturday's game.
The gaffer, who was speaking to Latics Player ahead of the game, believes Gillingham will be a hard outfit to break down but is calling on everyone to create a good atmosphere.He said: "It's a big game for us. We played well down there earlier in the season, winning the game 1-0 and they are a really good side. Peter Taylor has gone into the club and done really well. They've lost a few but they have got wins without drawing many.
"It's an important game for us. We need everyone to be lively on and off the pitch with the supporters. It's a good game for us to play at a high tempo.
"We've had to rebuild two or three times this year. It's been difficult to get a settled back four and team but we showed enough. We know we can put a little run together and it would be nice to start that against Gillingham."
With Genseric Kusunga suspended for the game, the manager gave an update into the injury sustained by Korey Smith.
"It's the best case scenario with Korey," admitted the gaffer. "We're hoping that he might be available at some point during next week. There was a serious fear that it could have been a season-ending injury but I'm the glad it's not.
"Korey is a big player for us. He's our captain and hopefully he'll be back sooner rather than later."
With Bobby Mimms leaving the club earlier in the week, the manager spoke about the current coaching situation regarding the goalkeepers.
"We've got a young lad in called Anthony, who is very keen. We've also got Paul Rachubka so we've got the line of thought where we could double up next season," said Johnson.
"Anthony is very hungry, spent time on his coaching badges and he's initiative in his thought process.
"I've nearly been here a year now and I know what's best structure wise for us. I know how to use the budget to the best effect and I'm certainly looking forward to implementing that in next season."
