PSG are considering benching Lionel Messi, Kylian Mbappe or Neymar in new formation

Paris Saint-Germain manager Christophe Galtier is considering dropping one of Lionel Messi, Kylian Mbappe or Neymar to try a new tactical approach.

Galtier has used a 3-4-3 formation since arriving in the summer and it brought huge success in the opening weeks of the season.

Messi, Mbappe and Neymar, collectively known as 'MNM', have thrived in the system and registered a whopping 41 goal contributions between them.

PSG have started leaking goals however and went behind against Maccabi Haifa in the Champions League on Wednesday.

According to L'Equipe, Galtier is aware of this vulnerability and may drop one of his front three for a forward more willing to press and track back or an additional midfielder.

Teams have started to attack the spaces left between the star-studded trio and PSG's wing-backs, which could be punished in Europe's elite competition.

The duo of Vitinha and Marco Verratti can be outnumbered in the middle of the park and that's something Galtier knows too.

Galtier is said to be privately questioning if PSG can win the Champions League with all three of Messi, Mbappe and Neymar starting together.

Messi, Mbappe and Neymar were all on the scoresheet out in Israel to ensure PSG kept their 100 per cent record in this year's Champions League.

PSG are top of Group H and are likely to qualify top of their group, given results around them. Benfica are joint-top on six points, while Maccabi and Juventus are both on zero.

Galtier discussed his side's performance in his post-match interview and touched on issues with his attack.

He explained: "It's not so much that the attacking trio didn't defend much. The team block was low, and the three of them quite high. They wanted to get the ball back as soon as possible, but it gave a lot of space behind their backs.

"We were really outnumbered in the middle. From the moment Messi, Mbappe and Neymar came back lower, in the team block, we started to counter their balls a lot better.

"We were then able to win the ball in important areas, and were better able to project ourselves offensively.

"It was not a question of bad will, but rather a bad analysis of the pressure between our midfielders and our attacking trio.

"As soon as Neymar was repositioned on the left side at half-time, it gave us a more interesting balance and we were able to recover the ball where it was needed."
