Former Barcelona sports chief Eric Abidal believes Lionel Messi will have a positive impact on PSG's players.
Abidal played with Messi and also worked with him while sporting director at Barca.
He told Canal+: "He will bring his experience. And as he said: every year he changes his game. It's true that he's not the same Messi as when he started. And I think the players around him are adapting, raising their level of play.
"It's important to have a competitive player who makes a difference. For PSG, it is another offensive asset. Everyone is eager to see the trio. Even if today, it is not limited to these three on the offensive plan. It's going to be a headache for the coach."
