What has been said? Carson claims Ederson will not be fazed if forced to face and convert penalties, with City's third-choice shot-stopper telling the Manchester Evening News: "He has smashed a few at me and Zack [Steffen] and it’s one of them where you actually want him to score, you don’t want the ball to hit you because he smashes it that hard. "It does hurt! He takes a few every now and then and seems to find the side-netting every single time, and with the power. It’s incredible." Could City go to spot kicks? There will be plenty of goalscoring talent on show when two Premier League rivals lock horns on a European stage in Porto, but contests with so much riding on them tend to be tight affairs.
