Paris Saint-Germain attacker Lucas Moura has insisted that his team must be wary of Barcelona's Neymar in their upcoming Champions League quarter-final.

Lucas, who plays alongside Neymar with Brazil, has described the Barca forward as "a football genius".

However, their friendship will be put to one side when the pair meet in the last eight of the European Cup this month.

"He's a football genius. I'm happy to say he's my friend and I'm pleased to see the kind of season he's having. I love to watch him playing for Barca. We have to be very careful with him," Moura has been quoted as saying by AS.

PSG, who beat Chelsea in the last round, welcome Barcelona for the first leg of their quarter-final on Wednesday.
