The defending Premier League Champions have struggled in both domestic and European competition this campaign, but will be buoyed by their 2-1 Champions League win over Dynamo Kyiv on Wednesday.
"That result was so important for us, because if we win one more game we can qualify from this group. But also it was important for our confidence," Matic said.
"In moments like this, it is important to win. It does not matter how you play. You can play well, or badly, but the only thing that matters is that you win.
"Now we have to win on Saturday. It is going to be tough, it is always difficult at Stoke but last season we won there 2-0 and we can do the same now.
"Maybe what we did on Wednesday will be good for us. Because it is not easy when you are playing well, and you concede a goal. But we recovered from that.
"If someone had told us before the game that we were going to win 2-1, we would have taken it."
