Cristiano Ronaldo missed his second Premier League game since rejoining Manchester United; Ralf Rangnick confirms forward has "problems with his hip flexor"; Sky Sports pundit Roy Keane: "We talk about Ronaldo being a machine and very rarely getting injured... it doesn't add up to me" With Edinson Cavani also absent from the matchday squad and Marcus Rashford on the bench, United's attack did not feature an out-and-out striker, with Bruno Fernandes, Jadon Sancho, Anthony Elanga and Paul Pogba operating in forward areas at the Etihad Stadium.
