It was Neymar’s chance to prove he was in the same league as Lionel Messi and Cristiano Ronaldo on Tuesday night.The world’s most expensive footballer took his PSG side to the Bernabeu to take on Real Madrid in the first-leg of their Champions League last-16 tie.But he couldn’t quite do that as his side fell to a 3-1 defeat to Ronaldo and co.As Ronaldo was bagging a brace to put his side on the brink of qualifying for the quarter-finals, Neymar struggling to make any kind of impact.In fact, he was struggling to stay on his feet in the early stages and was seen changing his boots after about 20 minutes.Eagle-eyed fans spotted Neymar change the brand new Nike Mercurial Vapor 360 to his old Nike Mercurial Puro Fenomeno.It was supposed to be the launch night for the new Mercurial's and Neymar was showcasing the boots on the world's biggest stage. By taking them off immediately against Madrid, he was basically saying he preferred the old boots.

That won't help sell the £230 boots and was definitely a marketing nightmare for Nike.And those football fans that spotted it think Neymar could be in big trouble - especially as Nike attempt to sell their brand new Mercurials.

FOOTBALL FANS REACT

Check out the reaction on Twitter:

Neymar also upset fans by storming off the pitch at full-time, without shaking hands with any Madrid players - or applauding the travelling PSG fans.

It seems it was a nightmare night all around for the superstar.

RABIOT ON PSG'S PERFORMANCE

And after the match, PSG midfielder Adrien Rabiot - who put his side 1-0 up - appeared to slam the attacking players for the difference in their performance from their 8-0 thrashing of Dijon in January.

"I am disappointed. We started by producing the match that we needed to.

"We always say the same things, we always do the same things, and in the end, we are always floored in the same way.

"It's all well and good putting eight goals past Dijon, but it's in matches like this that you have to stand up and be counted. It is very frustrating we let the match slip out of out hands in the end."

If Neymar wants to prove he can win the Ballon d’Or in the future, he’ll need to haul PSG into the last-eight of the competition with his performance in the second-leg.

He better get those boots sorted before that…
