The Camp Nou sporting director admitted that the Chilean is a world-class talent.
Arsenal’s chances of finishing in the top four this season took a blow at the weekend as Arsene Wenger’s men went down 2-1 against Tottenham at White Hart Lane.
The Chile international moved to North London in the summer and has been a revelation in the Premier League, scoring 12 goals and creating seven assists for his new club so far in 2014-15.
”I'd like Sanchez on at all my clubs, but sometimes can’t,” Braida told El Mercurio.
“I was not at the club at that time and I can not put myself in that situation. I only started my position this month.
“I do not know what reasons the club had to let him go, but now Sanchez is one of the best in the Premier League and is at a top level in world football.
"Alexis Sanchez is a great player, one of the world's best in his position. I know him well, he has an exquisite technique. Alexis Sanchez could have been one of my players and who knows if in the future he will be, you never know.”
Sanchez is in contention for a place back in the Arsenal team tonight, as Wenger’s charges host Leicester at the Emirates Stadium.
The Gunners sit in sixth place on the Premier League table currently, two points adrift of the top four and 14 behind division leaders Chelsea.
