The ex-Arsenal star, 30, has decided to quit Juventus after their relegation in the Serie A match-fixing scandal.
Vieira said: “Everyone wants to play for a club like Manchester United at the very highest level. It might be difficult after nine years at Arsenal but anything can happen in football.
“I will certainly not be playing for Juventus next season after they were relegated to Serie B.
“I believe my future will be sorted out in the next 48 hours.”
If Vieira goes to Old Trafford he will link up with midfielder Michael Carrick, who completed an £18.6million move from Tottenham yesterday.
Vieira joined Juventus for £13.7m last summer after nine years at the Gunners.
But with the Turin side dumped from Italy’s top flight and without Champions League football, Juve need to off-load their highly-paid stars.

어느쪽으로 가던지 상관은 없지만
