The 23-year-old was left out of Ajax’s pre-season friendly win over Eintracht Frankfurt on Saturday and United are expecting to wrap up a £40million deal for the midfielder imminently.
After helping fire the Eredivisie side to the Champions League semi-finals in 2019, Van de Beek carried on his good form last season.
The Netherlands international would have to compete with the likes of Paul Pogba, Fred, Nemanja Matic and Scott McTominay for his place in the side.
Bosnich believes healthy competition is a good thing and backs the deal as a good opportunity for both parties.
‘I think it would be a fantastic move for both the player and the club.’ Bosnich told Sky Sports.
‘Those that watched the player during his time in Holland have seen the progress that he’s made.
‘I think he’ll play more often than not. You can tell that Ole is trying to build a squad that will be sufficient for them to challenge on several fronts, not just for one particular competition.
‘He knows from his own experience from being at the club when they won the treble, they had four strikers – himself, Teddy Sheringham, Andy Cole and Dwight Yorke.
‘It’s very important to make sure you have back-up in each position.’
