It took a long time for Ruben Amorim to get Manchester United to become the best version as expected. He needs some additional players in defense, midfielder and attack, that can help his plans if he wants to make Manchester United improve. I know this is not an impossible mission, but it certainly requires a lot of money and time that is not instantaneous.
Success can be achieved by always trying your best and continuing to improve on shortcomings, but the problem is that many people are impatient because Manchester United has not been considered powerful in Europe for so long. The European League is certainly not an easy competition, but to win it requires struggle and a capable squad that can produce a good performance.
Which means Amorim can't do much other than maximize the available players, moreover it's not the right time to do a major overhaul. IMO, Manchester United actually has quite good players, but this team does need a precise formula so that the performance of its players is much more competitive. Well, what you said is true, if Manchester United is going to do a overhaul, they need a big budget and also have to release some of their players. One more thing, it is understandable if the die-hard supporters of The Red Devil can't wait for their favorite team to become an elite team again.The fact is, as we all know, there have been many coaches who have handled Manchester United, but none have been able to provide an achievement according to the wishes of The Red Devil supporters. What is clear is that Amorim will try to bring his team to the maximum, including for the Europa League, whether it succeeds or not, we'll just have to see the developments.
