Amakhosi will welcome Phunya Sele Sele to FNB Stadium for their second leg clash on Saturday, following their 1-1 stalemate two weeks ago.
'Shabba' says his side knows what is expected of them from both the fans and the club's perspective, and promises they are ready to go all the way to meet those expectations.
"In the second leg, we know what is expected and we will meet those expectations," says Tshabalala.
"It's going to be a tough game again. But with two games to go to retain the trophy, the focus is solely on the second leg against Celtic."
Following Celtic's Absa Premiership win over Chiefs' arch-rivals Orlando Pirates on Wednesday night, the 30-year-old adds that Clinton Larsen's men can now be considered "a big team in the PSL".
"I watched their game last night against Pirates; it was a completely new side but I think they did very well, they showed hunger.
"It shows they have quality in their team and they have depth, and it's a team we will not undermine.
"We've seen that they can hurt teams, and they are for me one of the big teams in the League. So we'll take that into consideration but we are also capable of hurting teams."
