United ultimately left their pursuit of the midfielder too late, with Dortmund already gazumping them with the promise of regular first team football.
It was a blow for Solskjaer, who felt Bellingham would have been the perfect long-term replacement for the likes of Ander Herrera and Marouane Fellaini.
United did end up bolstering their midfield in 2020 by landing Van de Beek, who had been shining with Ajax at the time.
Yet the Netherlands international is now considered a substantial flop, having made just four Premier League starts since moving to England.
This summer, United are set to try again for Bellingham with Ten Hag believing the 19-year-old can be a huge asset for many years to come.
