Chelsea boss Maurizio Sarri was delighted with the character shown for their 1-0 win at Europa League opponents Slavia Prague.

Marcos Alonso produced the winner on the night.

"I'm really happy with the result, and also with the performance," Sarri said.

"In this moment we are able to suffer, and in the past we were not able to suffer in the difficult moments of a match.

"In the past when we were in trouble, we immediately conceded a goal. Now we are able to stay in trouble to fight and to suffer without conceding anything."

He added: "We knew very well to play here is very difficult. The opponents are very physical, very aggressive, so we knew we had to face difficulties during the match. We were able to face them well, then in the second half we were able to play better.

"Now we need to think the second leg will be difficult. These opponents are also very dangerous away, like against Genk [where they won 4-1]. We need to be careful."
