Chelsea goalkeeper Mark Schwarzer is delighted for Tomas Kalas after his winning debut at Liverpool.
Both men were outstanding for the 2-0 triumph on Sunday.
Schwarzer remarked: "The manager asked various players where they made their debuts in the Premier League and they weren't very flash in comparison to where Tomas was going to make his debut. There was a bit of a laugh going around the room.
"We had no doubts about Tomas, he is a very talented young man and he's worked very, very hard this season."
