Bosnia-Herzegovina international Begovic kept clean sheets in all three of those games, but will now face a side who thrashed Lausanne Sport 5-2 at the weekend.
"From a defensive point of view, we have been superb so far, so we will go there confident of producing another solid performance," Begovic told stokecityfc.com.
"It will be tough - we know that. There are no easy rides anywhere when you are playing home or away in European competition.
"They are flying at the moment, but we are confident too. We beat a very good Hajduk Split side 2-0 in the last round and held Chelsea to a draw on Sunday, so we are going there looking to put ourselves in the driving seat."
