The New Zealand international ruled himself out of Leeds' win at Sunderland saying "I do not feel it is right that I play" and United boss Thomas Christiansen expects the move to go through after a medical.
Wood, who scored 30 goals last season, has been the subject of three bids from the Premier League side this summer and Leeds have accepted the third after Wood expressed a desire to leave despite being offered a new deal.
"Due to strong interest from a Premier League team, the ongoing discussions with the club, and given it has always been my ambition to play at the highest level, I don't feel it is right that I play today," he wrote on Twitter ahead of the clash.
