The Brazilian's 53rd minute deflected strike earned Pep Guardiola's men all three points in a dominant display in London.

The 24-year-old was delighted with his goal, but also made special mention of the performance of his teammates.
"We prepared the game to play well like we always try to do," he said.
"We came to play against one of the best teams, they’re European champions, they have a lot of amazing players, so we knew it would be difficult coming here at their home. We played very well and won the game.
"I play like a striker. I can never turn properly with the way they play but I turned good and I took the shot.
"It was a little lucky but I’m very happy to score the goal and most important is that we won the game and everyone played so good!"

"We have a lot of top players to create the chances and to score the goals. That’s what I think we have."
