The six-time world player of the year scored his first Paris St Germain goal as the French side avenged their loss in last season’s semi-finals with a 2-0 group stage victory on Tuesday.
Messi had been doubtful ahead of the game but proved his fitness with a stunning goal after 74 minutes of a compelling clash at the Parc des Princes, adding to Idrissa Gana Gueye’s early strike.
Pochettino was quick to point out, however, that Messi’s goal capped a fine team performance.
He said: “You need this type of performance for a player like him to be able to score goals and fill the net.
“Victories are always a collective and from the team. It is a team sport. The victory comes against one of the best teams in the world and one of the best managers. It is obviously a very good result and I am very happy.”
The result ignited PSG’s challenge in Group A after their opening draw against Club Brugge and lifted them above City.
Pochettino said: “The three points are really important. It wasn’t easy when City played really well but we managed to be really offensive and score two goals. I am pretty happy.”
