As Pablo Mari made his Arsenal bow this, playing 45 minutes against Chelsea for the U23s, teammates Hector Bellerin and Dani Ceballos watched on.
The Spanish duo were there to support their compatriot, who signed on loan from Flamengo last month.
Due to the Brazilian schedule, he hasn’t played since December and is still working on his fitness, but Arteta seemed pleased he had the support of his fellow Spaniards and admitted he’d been taken aback by the way the new man had trained.
“I was very glad that those two were there to support him,” he said.
“When he joined the club he hadn’t played for a long time and he had a little niggle as well well when he joined us, but his attitude and commitment has been really, really good and highly surprising.
“He did really well the other day and hopefully we can start to use him soon.”
Arteta was also asked about Matteo Guendouzi who was left out of the squad for the win over Newcastle following a bust-up in Dubai.
The boss refused to go into specifics, but again made it clear that he has standards that must be upheld if players want to be involved.
“It was about the way we train, the way we play, the way we live,” he said.
“I want the best players for the game and I select them in relation to what I see on a daily basis.
“I just make my team selection and the squad is selected in regards to how they play, how they train and how they behave.
“Every week it will be different. One week it will be one reason, another week it will be another reason.”
