Manchester United were convincingly beaten by Juventus to leave them five points behind the Italian champions in their Champions League qualifying group.
Paolo Dybala’s strike in the first half may have been a simple tap-in, but the build up and movement highlighted the difference in quality between the two teams.
Juventus played with their passive hosts in the opening period, with United left chasing shadows in a display of dominance which deserved a greater reward than just Dybala’s 17th-minute goal.
Ronaldo’s cross was key to the opener and the former United forward would have scored at Old Trafford just as he did with Real Madrid in 2013 were it not for an outstanding one-handed stop by De Gea early in the second half.
Ronaldo was cheered off the pitch at the end of a match that felt like a huge occasion from the outset.
