That’s the view of Liverpool hero Steve Nicol.
Starsport exclusively revealed this week that Arsenal and Manchester City are weighing up a sensational straight swap of their star men.
Discussions have been held about the South Americans switching clubs this summer.
City boss Pep Guardiola had made former Barcelona hitman Sanchez, 29, his No.1 striker target this summer.
And pundit Nicol has backed the proposed swap deal, claiming it makes sense for both parties.
"Absolutely 100 per cent (it would be beneficial for both teams)," Nicol said on ESPN FC.
"I think there's no question that Sanchez going to City elevates them and Arsenal 100 per cent need a world class proven goalscorer and Aguero is that man.
"From that point of view, to me it's an absolute no-brainer. I think the problem starts, not with Sanchez because I believe Sanchez likes playing in the Premier League, I think it suits his game, suits his style and Manchester City are on the way up, no question.
"The problem is Aguero, he is 29, this would probably be, whether it's Arsenal or anywhere else, his last major move. Does he want to go to a side that's not in the Champions League?
"Does he want to go to a side that realistically isn't going to win the Premier League next season and maybe for another couple of seasons, because they have such a big rebuilding job to do?
"I don't think he wants to stay at City if Gabriel Jesus is going to play ahead of him.
"At the same time, he's a world class striker. There are some big teams out there who I believe would want him.
"Do they have space right now? I don't think so, Bayern certainly don't need him, Madrid don't need him, Barcelona don't need him, PSG have Cavani.
"So if he wants to move maybe Arsenal is his best choice at the moment.
"Is it possible? Yes it is. It's up to the two sides to get together and I don't see why (Arsene) Wenger wouldn't want it, I don't see why Pep wouldn't want it. So really, it comes down to finance."
