Left-winger - Neymar Jr.
Neymar Jr. seemed disinterested as PSG fell to a shock 1-0 defeat against Nice in the weekend. Paris Saint-Germain have plenty of quality but when their players are outworked and outrun on the pitch, it's hard for them to be successful.
The weekend loss was a case in point and Neymar Jr. was one of the main culprits behind their fall. The Brazilian international's focus was off and he relinquished possession far too many times. He also seemed indiffierent to helping out his defence and his work rate was quite simply abysmal.
One cannot hope to go to the Santiago Bernabeu and expect to earn a positive result if they're not willing to bust a gut. Pochettino will be hoping that Neymar shows a lot more zip on Wednesday night.
Striker - Kylian Mbappe
Kylian Mbappe gave PSG a proper injury scare in training on Monday. Idrissa Gueye accidentally stomped on his foot in training and there were concerns over whether or not the Frenchman had sustained a fracture. He underwent an MRI scan and which confirmed that there was no fracture.
However, PSG released a statement on their website that read:
"Kylian Mbappe received a knock on his right foot in training today. He has undergone treatment this afternoon. The medical tests are reassuring and another update will be made in 24 hours."
Right-winger - Lionel Messi
Like Neymar, Lionel Messi was not in a very industrious mood against Nice. He continues to produce moments of magic when he is on the ball but Messi has to offer more when his team is out of possession.
He will be looking to knock familiar foes Real Madrid out of the Champions League and is expected to turn in a more well-rounded performance at the Santiago Bernabeu.
In 46 appearances against Real Madrid in his career, the former Barcelona man has scored 26 goals.
