Chelsea boss Thomas Tuchel is pleased with his players’ performance, despite the loss, and claims they deserved a clean sheet.

Tuchel told BT Sport: “It was a tough fight. Maybe not nice to watch on the television. It was very hard to play against them, very hard to escape the pressure. They are aggressive and attack in an aggressive way. They overlap, underlap, you have to adapt to many movements.

“With every minute we adapted better and better. We defended very well, deserved a clean sheet and had the better chances, not a lot. But we couldn’t finish them off. Overall, we deserved to beat Porto.

“Porto is a team that can make other teams underperform. It happened to Man City in the group stage and Juventus. So you have to accept things are very hard.

“Part of performances is to not let the other team perform and we did that today. Lucky shot in the last minute but we did not concede chances.

“I like it in Champions League not to play in teams from your own league, it gives the feeling more of a European competition. The game is far from over and I will watch it for sure. It’s a pleasure to watch it as a semi-finalist. It’s a great achievement and tomorrow we will watch the game. Everything is possible. We will take what we get”
