I don't think this is a good move, because Vlahovic is not in his best form and might be a problem to United that's trying to transform the club. I don't think that the deal is sealed up already but negotiation is still on. When the transfer window opens, we will see the players coming to United.
The EPL is known as a tough competition league and when players come from other leagues when joining the EPL, they will definitely have a little difficulty when the competition is very competitive. Well, that's what happened to Zirkzee who was considered to be impressive but in fact could not do anything. This could also happen to Vlahovic when he later comes and joins MU, he may not be able to become the player we expect. But it all depends on how the coach rotates the players and how big the mentality of the player is. As long as the agreement has been made and Vlahovic officially joins MU, I hope Amorim can provide the right direction for the attacking player.
