Manchester City manager Pep Guardiola was in attendance in Game 1 of the 2024 NBA Finals between the Dallas Mavericks and Boston Celtics on Thursday, June 6, at the TD Garden in Boston.

The Spanish football tactician was seated courtside with his spouse, Cristina Serra, enjoying a trip in America.

Guardiola wore a black Celtics hoodie with the green "Boston" wordmark, similar to the team's statement jerseys this season.

Widely regarded as one of the greatest football managers of all time, Guardiola is the only coach in the sport's history to win the European continental treble twice, with FC Barcelona (2008-09) and his current club Manchester City last season (2022-23).

The 53-year-old tactician was already present in the TD Garden a day before, as he was spotted during the media day and team practice on the same floor, engaging in a conversation with Celtics head coach Joe Mazzulla.

Mazzulla previously stated that he studies Guardiola and Manchester City a lot to help him guide this Celtics team, who won a league-best 64 games in the 2023-24 regular season.

"I study a lot of Man City. I study Pep a lot. I think he's the best coach at any level, in any sport. It's had a huge influence [on me]," the 35-year-old said.

The Celtics head coach visited a Manchester City team practice in February 2024 during the NBA All-Star break.
