Chelsea No2 Gianfranco Zola says there'll be changes for their Europa League clash with Slavia Prague.

The Blues will host the second-leg with a 1-0 lead.

Zola said: "I wouldn't say we put out a weak side when we played over there.

"We made changes because we know we have a good squad and players who can come in and do well, as we did over there.

"There will probably be some changes but there will not be many, because it is a tough match. We knew that before and the match over there confirmed that. We are very aware we are playing a good team and need to play at our best."
