One man who could prove to be key to the outcome of Champions League game between Manchester United and Wolfsburg is Nicklas Bendtner.
The former Arsenal striker never lived up to expectations during his time at the London club and also hit the headlines for the wrong reasons off the pitch.
His troubles continued at Wolfsburg, where he was made to train on his own after falling out with manager Dieter Hecking last year.
But the 27-year-old scored a vital equaliser and the winning penalty in the club's DFL-Supercup victory over Bayern Munich in August and is now a key squad member according to his manager.
"He has reacted very well. I have seen that in training," Hecking said.
"He did have problems before but in his time at Wolfsburg he has come on a lot.
"Certainly in the last four to six weeks I have seen more development from him. He is on the right track. That is clear.
"He shows that in training, perhaps with less of the extravagance that he showed in England before, so I think he is on the right track and he will definitely be keen to play."
Manchester United manager Louis van Gaal has admitted a result tonight is vital for his side in light of their defeat in their opening game to PSV Eindhoven.
"I think in the Champions League you need to win all your home matches otherwise it shall be very difficult," said Van Gaal, who lifted the trophy with Ajax 20 years ago.
"It is important we shall win."
