Ralf Rangnick thought Manchester United's pursuit of Bologna striker Marko Arnautovic was a joke while his three-player shortlist for the club was ignored.
Rangnick was appointed as United's interim coach in December on a deal until the end of the season but it had been agreed that he would continue at the club in a consultancy role for two years. However, that plan was subsequently scrapped as his exit was confirmed at the end of last campaign.
The 63-year-old took the reins of the Austrian national team to coincide with his United departure, where Arnautovic remains a star player and is the only member of the current international setup to have won more than 100 caps.
