The Chile international has been relentlessly linked with a move away from the north London side over the last few months as he approaches the final few months of his contract at The Emirates.
Both he and Mesut Ozil could be on course to leave Arsenal in the summer transfer window on free transfers if the Gunners fail to resolve their futures before then.
Sanchez is widely regarded as one of the Premier League’s top attacking talents and he was heavily linked with a move to Manchester City in the summer.
It remains to be seen whether the Chile star will still be an Arsenal player after the January transfer window, but it is clear that former Manchester United star Neville holds him in very high regard.
Speaking to Sky Sports, Neville said: “He is world class. He is genuinely world class. I mean, Pep Guardiola wants him at Man City.
“At his very best, he is a nuisance to play against on the ball and off the ball. He is a good defender as well.
“He harasses players, he scores goals and he is good in the air for a small player.”
Sanchez will be expecting to start for Arsenal when the Gunners return to Premier League action on Thursday night with trip to Selhurst Park to take on Crystal Palace.
Arsenal finished in fifth place in the Premier League table last season.
