We hold the upper hand going into the second leg of the tie after Jermaine Jenas’ fine strike secured a 1-0 win in the first leg in Prague.
That is one half of the job done but Chris and Martin Jol have stressed this week that there is still work to do at the Lane.
“The most important thing is not to concede and if that’s the case, we win the tie,” said assistant boss Chris.
“The longer the game goes without conceding means they will have to open up more and we can look to try and capitalise on that ourselves.
“Slavia changed their formation at the weekend to a 4-5-1 and then going into a 4-3-3, so whether or not it will be the same formation against us, we don’t know. They know they need to score and they showed enough in the second half in Prague to suggest that they can be dangerous.”
Slavia showed just what they can do away from home at the weekend when they hammered Viktoria Plzen 4-0, Pavel Fort bagging a hat-trick. "It's a confident side and we know we have to do our jobs right on the night," added Chris.
Chris Hughton is determined to deny Slavia Prague that precious away goal on Thursday - knowing a clean sheet will take us through to the group stage of the UEFA Cup.
