Considering the situation of Manchester United, the Glazer's are economizing their porse because of the situation on ground about the transfer of ownership should incase the club become sold to another person because Sheikh Jassim offer is still on the table and they are willing to buy the club any moment from now. But even with the little budget, they can bring in good men from other clubs that are willing to live their club for Manchester United, after all we have seen low budget players becomes good assets to another clubs, they don't need to target big players to win leagues.
If you look at Manchester United's statistics last season, you can say that Erik Ten Hag's composition is unstable, especially when several core squad injuries forced Manchester United to force reserve players to play with a different strategy. For example, when Martinez was injured and Casemiro accumulated cards, Erik Ten Hag pulled Shaw into the back line and Casemiro position saw many gaps.
Therefore, for the current budget, Erik Ten Hag is still unable to maximize the purchases he wants, but because Erik Ten Hag is quite creative, he tries to buy players at inexpensive costs. It was proven when Mount's offer was repeatedly rejected because it had not reached the agreed price.
Returning to competition next season, the task is quite tough in the Premier League. Liverpool, Newcastle and Arsenal will be tough competitors in fighting for their position in the standings. Meanwhile, Manchester City will still be at the top of the standings. That's the scheme in my opinion so far. It depends on how Erik Ten Hag prepares his players for the additional schedule in the Champions League which is much more difficult.
