Huub Stevens is not taking anything for granted ahead of Schalke's Europa League clash at home to Viktoria Plzen on Thursday night.

The Royal Blues scored an away goal in the Czech Republic a week ago, but the 1-1 draw means the tie is still open ahead of the second leg at the Arena AufSchalke.

"We still have one half to go," said Stevens.

"The chances of us going through are 50/50, maybe we even have a slight advantage from the first leg since we are at home."

A 0-0 draw would be enough for the Bundesliga side to reach the last 16, but Stevens insists he is not thinking about that.

"If we can, we want to win," he is quoted as saying on the Bundesliga club's website.

"And we want to build on our good performance against Wolfsburg."

Stevens expects to face a tougher task than his side did in the 4-0 win over the Wolves, though.

"Plzen have a lot of quality in their side and we saw that in the first leg," he added.

"They may not have any big names in their side like Barcelona or Real Madrid, for example, but they still play good football and are very compact."

Stevens may use Jermaine Jones, who is suspended in the Bundesliga, but both Peer Kluge and Lewis Holtby are injured and not expected to figure.

"They are not fit enough yet," said the Dutch coach. "But I will wait and see how our last training session goes before deciding on the line-up.

Plzen will be without captain Pavel Horvath, but his understudy David Limbersky will assume the armband confident they can pull off what would be considered an upset.

"I firmly believe we're capable of doing it without him," the defender said on www.uefa.com.

"I have never been captain in a more important game in my life. Theoretically, a goal would suffice, but it will be very hard not to concede so I hope we score more than once."
