Chelsea ace Mason Mount insists the tie is not over yet but is pleased with the result at Seville.

Mount told BT Sport: “We knew it was going to be a tough game. We knew how hard to play against them, we didn’t have many chances, but we kept going.

“We obviously got the goal first-half, and the second late on secured a good win, but that’s only half the tie. It’s about time it came [a Champions League goal], it’s a good time for it to come. It was a good pass by ‘Jorgy’ [Jorginho] and I just had a bit of space, so I just hit it after my first touch, and yeah, it went in, so obviously I was very happy with that. it took us in at half-time 1-0 up and in a good position.

“I’m always working on my finishing. I don’t think you can work on it enough, so yeah very happy to score one tonight but most importantly get the win. Chilwell showed great composure, to be fair. Very good finish from him, he’ll be buzzing with that.

“We definitely needed a reaction tonight [after the West Brom defeat]. After the game, we put it behind us, and we said, we need to improve. We’re getting better and better. That game was something we looked at briefly the next day, and we moved on.

“The job’s not done. We’ll be ready [for the second leg]”

Chelsea boss Thomas Tuchel echoed Mason Mount’s statement by insisting the tie is not over yet but described the result as “excellent” even though they “suffered” at times.

Tuchel told BT Sport: “The result is excellent. It was a tough match against a strong Porto side. They are a proud club and a proud team, so there were moments when we suffered. But we accepted it and I could see the circumstances are a bit different in a quarter-final.

“In some moments it was a good game, in some moments we suffered. But the spirit was good.

“I was pretty sure [there would be a reaction to the West Brom defeat] because I saw the response after the game in the dressing room. That wasn’t a big concern. We had a big loss but it was our responsibility but we accepted it. We were ready to respond. There will always be setbacks in football, the challenge is to bounce back.

“I am very, very happy he [Mason Mount] scored. It was an important goal and opened up the game for us and calmed nerves. It wasn’t an easy shot but very precise. I am very happy for Mason, he takes responsibility. Mason is precise with his finishing and always ready to help us.

“Was [Ben Chilwell] excellent because he kept his composure to go past the goalkeeper. It was super important to get the second away goal. Like I said, we lacked a bit of rhythm in our attack but there was always a chance to get a goal from a mistake from our opponent. He isn’t a regular scorer but I am very happy we go away with the result. It’s half time, though. We need to keep going.”
