Muani is on-loan at Spurs from PSG and struck twice in their 5-3 defeat to the Champions League title holders.
The France centre-forward was praised by Spurs manager Thomas Frank afterwards and he also said at the final whistle: “We’re a little disappointed as we started the game in such a positive manner.
"We managed to open the scoring, but we were unable to keep the lead in the end. The coach told us to keep working.
“It’s always nice to come back here, but football isn’t an individual sport so I’m a little disappointed given the result.
“We’ve done well so far, but we’re going to have to keep working as hard as possible in order to accumulate the maximum points we can going forward.”
