Lionel Messi scored his first club goal in a non-Barcelona shirt and it came against Pep Guardiola’s Manchester City. Paris Saint-Germain, riding on the goals by Idrissa Gueye and Messi beat City 2-0 in the Champions League group stage on Tuesday.

Messi netted an astounding 672 goals for Barcelona but it was his first for PSG in three starts and four games overall since a shock summer move from the Spanish club.

Messi had scored numerous goals of this kind playing under Guardiola at Camp Nou. The pair won the Champions League in 2009 and 2011, with the six-time Ballon d’Or winner scoring in both finals.

“I’m very happy to have scored. I’ve not been playing much recently and I’m adapting to my teammates little by little. The more we play together the better it will become. We need to grow together and increase our level,” Messi said after the game.

City had not lost its five previous meetings with PSG, winning 2-1 in Paris and 2-0 at home in last season’s semifinals before losing to Chelsea in the final.

PSG started its dream attack of Messi, Neymar, and Mbappe, but it was unheralded midfielder Gueye who opened the scoring in the eighth minute.

He thumped the ball into the top corner after Neymar’s scuffed shot fell to him just inside the penalty area following Mbappe’s cross from the right.

City should have equalized in the 26th, but instead produced a contender for miss of the season.

Raheem Sterling’s header from Kevin De Bruyne’s cross hit the crossbar and the ball fell to winger Bernardo Silva less than two meters out. But Silva somehow scooped the ball onto the bar with goalkeeper Gianluigi Donnarumma beaten.

Donnarumma and opposite number Ederson then made a smart save each in an even first half that De Bruyne was perhaps lucky to finish, receiving only a yellow card for a dangerous tackle on Gueye’s shin.

Sterling dragged a shot wide early in the second half as City caught PSG’s defense asleep down the left.

Donnarumma then kicked away De Bruyne’s shot in the 54th as City exposed poor defending on the other flank as the Premier League champion took control.

PSG’s glittering attack looked flat, as it did in a 1-1 draw against Club Brugge. Neymar shot into the side netting midway through the second half, with Mbappe in a better position.

Then Messi lit up Parc des Princes with a glimpse of things to come, at the stadium where he scored his last Champions League goal for Barcelona last season.

PSG tops Group A and is level with Club Brugge with four points, while City is third with three points. Club Brugge won 2-1 at last-place Leipzig.
