I can't understand this mindset. What promises do people think were made to him? Unless Donny is completely delusional he knew full well he wasn't coming in to replace Pogba or Bruno and in no reality did Solsjkaer tell him anything different. His best chance to win a starting spot for this season was to displace either Fred or McTominay but I don't believe for one second he was promised he would be an automatic starter, he needs to earn it just like any other player at the club.
You can argue over minutes but the fact is he played in 26 games in just over half a season and made 11 starts. If you go back and watch those performances objectively he was a level below the players he is trying to replace.
Ah the wikipedia stat? If so that includes national appearances, and given how sporadic he's been given his chances, I think context helps here:
He's made only 2 Premier League starts and accumulated something like 311 minutes in the Premier League, which is under 3.5 matches (PL minutes from
https://www.transfermarkt.co.uk/donny-van-de-beek/leistungsdaten/spieler/288255).
There should be a big buffer given for players who 1) come from a different country and 2) adapting to a big club like ours, but in his case, there needs to be additional consideration given he's 3) played a bulk of his minutes in the league off the bench where it is very difficult to develop match rhythm.
There are examples where he has not been good, there are examples where he has been good. Objectively speaking, I did not expect VDB to make a huge impact, I don't rate him as highly as a player when he was at Ajax either. However I do think he has strong potential, and by way of a box-to-box player he can develop into a better option than what we see from McT or Fred. And yet he features behind both, which I did not appreciate. Whilst not having played on the right, I think the way we play with a narrow right sided midfielder rather than an out-and-out winger, he could have been given opportunities there too. His skill-sets are not limited to just being a 10.
Promises would have certainly been made by the manger not in granular "you will play x games" but by way of his status in the squad. It's evident Ole did not sign him under the pretence that he'd make 2 league appearances and league minutes barely equalling 3 matches. So I do feel, promises were broken. I'm not exploding at Ole for it, because it's the nature of the game but I do heavily sympathise with the player. But I don't think VDB needs to replace anyone per say, but his standard is actually equivalent to or greater than the minutes he's been trusted with.
This season lacked a true pre season or friendly games and of course that had an impact on his preparedness but that in no way means he should be gifted a spot in the side when we are trying to win games, the team is picked on merit. It is on Donny to grasp his opportunities when they are given to him and his body of work to date clearly shows that he has not been able to do so. If he is now agitating to leave then it suggests he lacks the mental makeup to succeed here, he would hardly be the first Ajax star to fail in the PL or the first big money signing we have made who has wilted under the pressure.
I do hope this is just tabloid nonsense though. With a year under his belt and a probable return to normality next season including a real pre season I hope that he can kick on as there is clearly a good player in there.
Don't think anyone is insinuating he should be gifted spots, but I think his qualities certainly warrants more starts than he's given. I think Ole was likely planning to bring him into the fold in the final 3rd of this season, forward planning into this season, but he got injured at a bad time. Ole didn't really introduce Greenwood in a run of games until the second half of last season, he had a long period where Dan James was not turned to before bringing him back too. There are phases Ole seems to work with regarding younger talent, and I wouldn't be surprised if the approach was cautious with VDB.
I'm unsure whether I am being too presumptuous on my side here, but my guess is Ole knows he has a very good talent but also a player accustomed to a style of play that can't suit the team yet. He needs VDB to adapt to his direct counter attack style, but ultimately also needs to adapt to him as the long term project for the club is to dominate games in possession too.
So as you said, there is clearly a good player there and he should kick on next season, I hope!
