"Petr has played a big part in Chelsea's start to the season," said Baros. "He is a very good goalkeeper and it won't be easy to score against him.
"I know all about him because I played with him at junior level and also for the national team. I'm well aware what he's capable of.
"Chelsea are a very strong side. They are good defensively as they've only conceded one goal in seven league games so it will not be easy to break them down. But every game is difficult and we'll be ready.
"The result and the points are the most important thing."
