The 24-year-old, signed from Ajax for £35million in 2020, has played just 64 minutes of football in all competitions for the Red Devils this season.
Following a disappointing debut campaign at Old Trafford, the Netherlands star still can't get a game this term, starting just twice - in the Carabao Cup exit to West Ham and the Champions League defeat to Young Boys.
Van de Beek arrived from Amsterdam with a big reputation and his ongoing struggles have left many confused, especially given a perceived lack of quality in the current United midfield.
And Ince, a former teammate of Solskjaer, is among those baffled by the manager's treatment of Van de Beek.
The Dutchman has been given a number of short cameos this season, most recently playing four minutes against Atalanta and ten minutes against Manchester City.
With no time to influence the game and impress, Ince suggests Solskjaer is just making a mockery of Van de Beek.
"Donny van de Beek gets four minutes against Atalanta. What worries me is the choices Ole makes," Ince told the United Stand podcast.
"This is a player who Ole said, 'Come to Old Trafford, you're going to start in my team, you'll cost £40million, you're going to be the centre hub of the midfield'.
"This is what he said and Donny thought, 'F*** me, this is my dream, this is what I've been waiting for'.
"Two years down the line he's on the bench. Ole's actually taken the p*** out of him.
"Not only has he taken the p*** out of him, he gives him four minutes against Atalanta and then goes, 'Oh by the way, here's your chance, go and have 10 minutes against Manchester City where we've not touched the ball for 85 minutes and show me what you can do'.
"If I'm Donny van de Beek I would've said, 'F*** that, I'm not going on now, you want me to go on for 10 minutes when we haven't touched the ball for 88 minutes?' Now you're taking the p*** out of him even more.
"It's decisions like that baffle me, they really do. I don't understand.
"He stopped Jesse Lingard from going to West Ham because he said he'll be part of his team. You're 2-0 down and you don't bring him on.
"You see the situation with Paul Pogba now, he's starting to get sent off all the time, all that is starting to flare up again. He'll be gone by the end of the season."
