Erling Haaland has made an immediate impact for Manchester City on debut against Bayern Munich, scoring the game’s only goal after just 11 minutes on the pitch.
He finished off a Jack Grealish cross from close range at Lambeau Field, home of the NFL’s Green Bay Packers.
The Norway international, one of the hottest young prospects in Europe, left Borussia Dortmund in Germany for City – the club his father Alf Inge previously played for – in a deal worth PS51million ($A88m) in June.
The match in Wisconsin was delayed for 15 minutes by a thunderstorm, and play was suspended until further notice shortly after Haaland’s goal.
Fans were urged to take shelter on the concourse as lightning descended on the area and players left the field.
Officials then announced a reduced game, with 27 minutes left in the first half and a 40-minute second half.
The interruptions appeared to impact both side’s momentum, with neither managing to clinch another goal over the total of 80 minutes play.
In Orlando, Arsenal thumped London rivals Chelsea 4-0. First-half goals to Gabriel Jesus and Martin Odegaard were followed up in the second 45 by Bukayo Saka and Albert Sambi Lokonga.
