Chelsea midfielder Willian was relieved after their 1-0 win at Slavia Prague.

Marcos Alonso proved the matchwinner for the Europa League quarterfinal first-leg clash.

Willian said: "The game was very difficult. They have a good team.

"It was difficult to press them high because when we tried, they kicked long balls and attacked with the full-backs at the same time. We tried to press them as high as we can, but it was difficult.

“At least in the second half we scored the goal. It was a great result. It was a good ball for him and he scored the goal. Now we have the game at home. Today we did a big boost for the next game."
