The home side should choose a fairly strong team for this game, with exciting youngster Vaclav Kadlec a key threat in attack.
He would be supported up front by Albanian Bekim Balaj, who has scored five goals in 10 appearances since moving from KF Tirana.
In defence, the experienced Tomas Zapotocny will be crucial in the centre, hoping to use his considerable experience of European football to good effect for the home side.
For Chelsea, Demba Ba is cup-tied having played in this competition already for Newcastle, so it will fall to Fernando Torres to lead the line.
Blues manager Rafael Benitez may choose this competition to experiment with his side, allowing some of his fringe players time on the pitch.
John Terry remains out with a knee injury, while midfielder Oriel Romeu (knee) is another who is a long-term absentee.
