Edwin and Holger Quintero were signed this week from Independiente del Valle.
The 16-year-olds will both head to north London in August 2027 after turning 18. Both players are Ecuador U17 internationals, with Edwin a winger and Holger a midfielder.
"Well, there is certainly something that I think is very positive,” said Arteta on Friday. “I mean, we can recruit the best talent that is out there.
“Obviously the rules and the limitation that the league provides in relation to using them before a certain age, it is a challenge.
“But we saw that as a good opportunity for us and if we are ahead, I think that’s something very positive.
“For me, the first intention obviously has to be to develop our own players in-house, but that doesn’t mean that you have to close any doors for any talent that we have. That goes for players and it goes as well to staff I think.”
