Isco has warned his teammates, that the slightest error against PSG will not go unpunished, as they prepare to take on the Ligue 1 club.
Both Madrid and PSG have won their opening two UCL matches, with Madrid visiting France on Wednesday to see who will lead the group.
And Isco feels both teams will face each other carefully, but the midfielder thinks Madrid has what it takes.
“PSG are a very good, strong and complete side,” the midfielder told BWIN.
“They have some great players – ones who can decide a game on their own – they’re quick and strong.
“So I’m expecting two very tough games and both of them will be decided by small details – whoever makes the slightest error will get punished.
“Having said that though, they’ll be up against a Real Madrid side who have good qualities too and who can pack a punch in attack.
“I don’t think there will be a lot of goals, but I hope that if there are any goals, they’re all for us.”
