El Mercurio says Vidal has informed United he wants to join them this summer and it's now up to the fallen English giants to negotiate a fee with Juve.
United's contract offer - worth over twice Vidal's current Juve wages - has turned the Chile international's head.
Vidal has told United he won't force a move and has ruled out making a transfer request. It will be up to United to thrash out terms over a transfer fee with Juve.
Juve have already lined up a replacement for Vidal, with Romulo's move from Hellas Verona due to be confirmed today.
