We don't need "rebuild" because rebuilding term is one huge BS. Just like terms United Dna, knows the club etc...
This gets thrown around here more often than I thought. For what its worth - I wouldn't talk about "another" rebuilt, it is rather one big rebuilt starting with SAF already and never really finishing. Under SAF the team was in need of re-juvenation, Rooney, Rio, Vidic, Carrick, Evra - you name it, all of their careers came to an, and their replacements didn't really take the trajectory that was hoped (Smalling, Jones, Welbeck, Zaha). When SAF stepped down, Moyes had a big task, take over from one of the most competent managers ever and take over a squad in need. He didn't do much, his targets seemed erratic, the less said about it, the better. LVG took over, he cut the grass, got rid of quite a few players, added new ones with potential and instilled a new possession heavy style. Had we continued with him, he would have completed his rebuild but we didn't. We disrupted that rebuilt by going for Mourinho and giving him lots of decisions to make. He axed a few of LVGs players, added new ones, got rid of the possession heavy approach and added... well his approach. He went for different players, looked for different things in youth players. And he crashed and burned. Then we got Ole. A more individualistic approach, less constraints, more transitions. He more or less took over the Mourinho players and created something new. Aiming for the right characters, hoping to achieve the same thing as Fergie by selecting the right players who then will figure out the system on the fly. While Ole talked about pressing and quick attacking football, he added Maguire and AWB finally even Ronaldo. And here we are... sitting on a mixture of players picked by various managers, asked to play different football styles.
As others have said, a club built consists of a recruiting strategy, an idea about how to play a match, the right players and the right manager to glue everything together. We had no recruiting strategy for quite some time and to be perfectly honest, while the hopes are high, we don't know if that has already changed. With Ralf we have someone who has an idea on how to play, but he will be gone in a couple of months so do we have an overall idea on how to play? Can't answer that positively as we are missing the information. Do we have the right players? That depends on the system because the best players don't help you when you cant utilize them. I'd say we have pretty good players but what we are missing (due to all this mess) is a backbone of players who are leading figures - not just for their characters, but because their performance levels are mostly stable. It kind of is a hen and egg issue - what comes first? The system? Do you select players based on the system? Or do you select the system based on the available players? Again very difficult question. But the key task right now is get rid of variables. Either choose a manager or a DOF who will decide on general playstyle (attacking, defensive, proactive, reactive, high block, low block). Then add players to the roster that fit that playstyle. Let the leading figures emerge from the squad by having a good composition of great players in their prime years, bolstered by hungry talents with the potential to get in to the starting eleven and older players who lost the fight for a spot in the starting eleven.
As some have stated, our competitors are years ahead... We can't just throw money at the problem, some of the processes are organic. Lets hope, we have the decision makers in the club who understand that and will now built a foundation for the next cycle. We have very promising players in the team, Rashford, Greenwood, Sancho... maybe Dalot, Henderson, McTominay. There is great potential for new success but he have to get our act together. And we shouldn't just restart over and over because we don't like the results in a certain period of time.
