Paris: With two wins and six goals scored — including two each for Brazil star Neymar and World Cup winner Kylian Mbappe — Paris St-Germain seem to have made the perfect start to their title defence.

But things could have taken a completely different complexion if not for some fortunate decisions on Saturday.

Before Mbappe scored twice away to Guingamp in a 3-1 win in the French league, PSG would have been in big trouble without VAR.

Leading 1-0, Guingamp had a headed goal disallowed after use of the video assistant referee led to the actual referee deeming there had been a foul. Images and replays, however, proved inconclusive.

Then, with the scores at 1-1, Guingamp should have had a penalty after midfielder Marcus Coco was clearly fouled. Yet there was not even a VAR review.

PSG made the most of the reprieve as the 19-year-old Mbappe netted twice to underline his reputation as one of the world’s best players.

“Individuals made the difference,” PSG coach Thomas Tuchel told Guingamp coach Antoine Kombouare after the game.

It was a short but revealing comment because, beneath the veneer, things are not as smooth as they seem at PSG.

The troublesome Achilles heel from previous seasons — a lack of teamwork — still seems a major concern.

In the previous match, a 3-0 home win against Caen, PSG looked lacklustre but were gifted two goals by glaring errors.

Although Tuchel and Mbappe insist Neymar is PSG’s leader, he is not playing like one.

Against Guingamp, Neymar won and scored a penalty thanks to a piece of trademark trickery but — like against Caen — otherwise made little impact.

Late in the first half, Neymar even reproached 20-year-old teammate Christopher Nkunku for shooting from the edge of the penalty area rather than passing to him. Yet as an attacking midfielder, this is precisely Nkunku’s remit.

Last season Nemyar bickered with striker Edinson Cavani — no less than PSG’s all-time leading scorer — over who should take a penalty.

VAR let PSG off but Marseille were let down by it.

Late in the first half of Marseilles’ 3-1 defeat at Nimes on Sunday, forward Valere Germain was clearly yanked back by his jersey as he went to head the ball following a free kick.

Even though Germain was pulled to the ground by midfielder Teji Savanier there was no review.

The idea of VAR was to eradicate errors, but it appears to be prone to mistakes from its own officials.
