United are guaranteed to go through and can only top the group with a win along with a shock Juventus loss away to Young Boys.
So it should come as little surprise to see Valencia's Caped Crusader wearing a pair of Adidas X18s with Batman logos on the heels against Manchester United in the Champions League on Wednesday.

Pogba had United's best opportunity to cancel out Soler's impressive opening strike following a Marouane Fellaini knockdown but somehow missed the target from close range with the goal gaping. "I don't think we were brilliant in this group phase but we did enough to qualify".
It was his fourth own goal for United and possibly his most embarrassing, sliding the ball past his own goalkeeper, Sergio Romero, from the edge of the area. Massimiliano Allegri's side needed a victory in order to ensure first place finish in a tough group if Manchester United were to beat Valencia.
And it validates the reason why he was so desperate to sign a high-profile centre back in the summer, only for United's board to deny him funds.
"We achieved our objective by winning the group, even on a night where everything seemed to go wrong", Allegri told Rai Sport about Juventus' UCL campaign.
There were 43 minutes left but a United comeback never looked likely until Rashford, on as a substitute, headed home in the 87th minute.
To make matters worse, his habit of making unusual faces while he plays football - a trait often mocked online - was picked up by Chelsea loanee Batshuayi.
