The Ikon Allah will face Ladan Bosso's men who are yet to suffer a home slip since losing 3-1 against Akwa United on March 30, 2016, when they meet in a Week 13 encounter.
And Bala insists his side can replicate their good form against Enugu Rangers and Remo Stars in Maiduguri to bring El Kanemi's home winning run to an end.
"I'm happy with what the boys are doing, we are taking all games as they come with all seriousness and determination," Bala told media.
"That was reflected in our last game against Nasarawa United and I believe we can still improve as there are rooms to do better.
"We are going to approach our next game with a special pattern. It’s even good a lot of pundits will not give us a chance.
"We can get something from Maiduguri, but it's a plus for us as all pressure will now be on Elkanemi on Sunday.
"I'm sure, we will surprise everyone at the end of the day, and this was how we went to Enugu and got a draw against Rangers when nobody could see us getting anything there, the same thing with Remo Stars.
“We hope for a better and friendly atmosphere with a prayer for luck, I'm sure you will all be shocked with the outcome of the result on Sunday," he said.
