Neymar and Kylian Mbappe are doubts for Paris Saint-Germain's Champions League clash with Liverpool next week after coming off injured in friendlies for Brazil and France on Tuesday night.
Supporters who bought tickets for v Cameroon at Stadium:MK to see Neymar were left bitterly disappointed as he came off injured after eight minutes.
Mbappe, playing for France in a friendly against Uruguay in Paris, was forced off after 36 minutes with what appeared to be a shoulder injury.
It casts doubt over their availability for two of Paris Saint-Germain's next games but Neymar posted on Instagram after the match: 'Thanks for all of the messages wishing me a good recovery. I think it was nothing serious.'
Following the game, Brazil manager Tite refused to comment on Neymar's injury. Staff for the Brazil team added that it was PSG's place to confirm the severity of the injury, not theirs, although team doctor Rodrigo Lasmar had told Brazilian channel Globo TV during the game that it was too early to tell whether he would be out.
'He came off complaining of pain,' said Lasmar. 'He felt a discomfort, he will need a bit more time to evaluate it and take a scan, but in principle it is not a serious injury.'
