Both Manchester United and City are now 16/1 at Sky Bet for the Champions League after Wednesday's action in Europe.
The former were held to a 1-1 draw by Shakhtar Donetsk having taken a 1-0 lead while Manuel Pellegrini's men suffered a 3-1 loss at home to holders Bayern Munich.
The latter are the 3/1 market leaders at Sky Bet to retain the trophy ahead of 9/2 Barcelona and 5/1 Real Madrid.
Real beat FC Copenhagen 4-0 while PSG are 14/1 chances alongside Chelsea following a comfortable victory over Benfica 3-0.
Sky Bet's Sandro Di Michele said: "Things weren't looking good for much of the night with United popular at Shakhtar and most of the best-backed sides going well.
"But late equalisers in the Manchester United and Juventus games saved us. With the results on Tuesday night, we were desperate for a few upsets and the two tonight got us out of jail."
"Bayern were really impressive and deserve to be clear favourites on a night which also saw Real cruise to another comfortable win."
