Thomas Tuchel says Chelsea's reaction after losing to West Bromwich Albion has brought the team closer.

The Blues claimed a crucial 2-0 away over Porto in their Champions League quarter-final first leg on Wednesday.

The performance was a far cry from Saturday's insipid 5-2 loss to Albion.

And Tuchel believes the defeat and subsequent reaction has helped build trust within his squad.

"It was a tough match against a strong Porto side," Tuchel told BT Sport.

"There were many moments where we suffered. We accepted it. The circumstances are a bit different in a quarter-final. The spirit was good and it was an excellent result.

"I was pretty sure about that [they'd react well after the WBA defeat]. I saw a response immediately in the dressing room and the next day. That wasn't a big concern. We were ready to respond. There will always be setbacks in sports. The biggest challenge is to bounce back.

"We had a lot of excellent results together, then we had a loss together and then a reaction after a loss together. That brings us closer together and increases the trust.

"I'm very happy that he [Mason Mount] scores. A very important goal that opened up the game. It calmed the nerves. Not an easy shot but very precise. Very happy for Mason. He took responsbility.

"[Ben Chilwell's goal was] excellent. He kept composure and went round the keeper. It was super important to get the second away goal. Chilly forced the mistake and kept his cool in the box. We're very happy to go away with this result but it's only half-time."
