Chelsea boss Thomas Tuchel admitted that he got “nervous” after Mehdi Taremi’s screamer.

Tuchel added that Mateo Kovacic got injured before the game and will miss Saturday’s FA Cup semi-final against Manchester City, which is why he had to risk with N’Golo Kante.

Tuchel said: “I was still nervous because a goal can change anything, even if it is a crazy goal or bicycle kick like this, it can happen.

“I can imagine both games were not the nicest games to watch on television, I can totally accept, but it is very hard to play your best game against Porto.

“He [Kovacic] had a little injury out of nothing. I am sure he is out for the City game as well, very sad for him.

“We took the risk with N’Golo, maybe not a risk but the situation. We put him on the field and hoped he had the energy for 90 minutes.

“N’Golo is incredible, he is like one-and-a-half or two players, everyone loves him. He wins so many balls, gives everybody confidence. We were not sure if N’Golo would have started today but now it is time to recover good”
