Viktor Gyokeres was introduced to Arsenal fans before the game
BBC Sport football news reporter in Singapore
New Arsenal striker Viktor Gyokeres was introduced to the crowd in Singapore while 15-year-old Max Dowman once again impressed as the Gunners beat Newcastle 3-2 in pre-season.
Gyokeres completed his £64m move to the Gunners from Sporting on Saturday and waved to fans from the pitch before kick-off.
However, the Arsenal fans inside the National Stadium did not get long to enjoy the moment as Anthony Elanga scored his first goal in Newcastle colours with a scuffed effort after Sandro Tonali picked him out inside the box in the sixth minute.
The Gunners did have chances through Kai Havertz and Ben White but eventually drew level when Mikel Merino finished well from a clever Havertz flick on in the 33rd minute.
Just two minutes later Arsenal were in front when Havertz's low cross was slammed into his own net by Newcastle left-back Alex Murphy.
Newcastle made nine changes at half time and Arsenal almost extended their lead when Nick Pope saved well from an acrobatic effort from Bukayo Saka.
It was one of those nine subs who then drew Newcastle level when Jacob Murphy was allowed space to shoot from the edge of the area and the ball bobbled past David Raya.
Arteta once again brought on highly rated 15-year-old Dowman and the forward won a penalty following a skillful run, with captain Martin Odegaard scoring from the spot to give Arsenal the win.
Arsenal travel to Hong Kong next week to play rivals Tottenham Hotspur while Newcastle take on Team K League in South Korea.
Gyokeres steals the show
As soon as it was announced before the match that Gyokeres would be arriving in Singapore, the pre-season friendly was not going to be the most important topic of the day.
Supporters in the stadium were mimicking the trademark celebration of the Swedish striker and, when he was welcomed to the pitch from the tunnel surrounded by flames, the noise levels went up a notch.
The 27-year-old forward has not trained with his new team-mates and came straight from the airport to the stadium to greet the crowd.
Germany forward Havertz has done an excellent job leading the line for Arsenal over the past couple of seasons but Gyokeres is the type of traditional centre-forward Gunners fans have been crying out for.
The only real worry from the match for Arteta was that Riccardo Calafiori limped off just two minutes into the second half and was replaced by Jakub Kiwior.
Howe pushes Newcastle on
Just like Arsenal, it is the conversation around a Swedish striker that has dominated the club's time in Singapore.
Alexander Isak is considering his options amid interest from Liverpool and manager Eddie Howe has had to field numerous questions about his striker's future.
Howe said that the club is looking to do business in the transfer window in the time that remains and that whatever happens with Isak's future "has to be right for Newcastle".
Another Swede Elanga, one of Newcastle's few summer arrivals so far, got his first Newcastle goal and was a bright point in attack alongside William Osula.
