Neymar gave Barcelona fans a dazzling reminder of what they could be about to lose on Saturday, scoring twice as the Spanish giants defeated Juventus 2-1 in a pre-season friendly.

The 25-year-old Brazilian superstar is at the centre of frenzied speculation linking him to a gargantuan, world record 222-million-euro ($256.8 million) transfer to Paris Saint-Germain.

Neymar broke clear after only four minutes but saw a tame shot from near the edge of the area drift away from the goal.

He grabbed his second, picking his way through a static Juventus defence before burying a low shot beyond Buffon once more.

Neymar might have had a hat-trick three minutes from half-time, when Messi floated a delightful pass in behind the Juve defence for the Brazilian.

Man of the moment Neymar departed the stadium without addressing reporters, while Barcelona coach Ernesto Valverde could only repeat his desire to keep the Brazilian.

“We want Neymar to be with us,” Valverde said. “We know his value on the pitch and what he brings to the locker room.”
