Luckily DvdB hasn't suffered any injuries since arriving at OTVeron was a slightly different story Fergie wanted to change his style for Europe and go 1 up front as he felt the 4-4-2 was no longer working in Europe he saw we needed more control, this was around the time Queiroz also arrived. Veron became available due to a passport issue in Italy and Utd pounced but he never really gelled with Keane and Scholes found that new advanced role tough as as a 3 I don't think they ever really worked. Always felt like Keane and Veron were two players trying to do 1 mans job both were really good short passers that wanted to be in the middle of that three. That said it did really come together in 2002-03 when we won the title back from Arsenal Keane missed quite a lot of that season with injury and Veron from memory was good that season so it was a bit of a shock that we sold him that summer.
Veron came as a starting player went straight into the side whereas Donny I think from day one was signed as a squad player we never saw him as a starter and key part of the team. Felt to me like they hoped he could be a bit of a utility man but he feels a bit jack of all trades master of none in this side my worry with him is to get the best version of him he needs to be in a specific role which we don't have for him.
Donny made his name as the goal scoring midfielder in the Ajax team he was the most advanced of their 3 always breaking into the box and he was great in tight spaces around the box. This was the most eye catching part of his game yes he could do all the short passing and rotation you do at Ajax but really he was a goal scorer from midfield and that's what caught a lot of clubs attention. De Jong was always the guy in midfield who controlled the game which is why Barca were so desperate for him although I hear he's really struggling this season.
A player who arrived the same summer as Donny but cost a bit more money was Partey I think he'd have been great in our midfield two but I think we dodged a bullet with him as he's injured a lot. Arsenal spent £50m on him but feels to me like he misses about half the games with injuries but when he's fit I think he looks a good player.
