I don't think Manchester United will be able to make huge expenditures in the mid-season transfer period. Because in these periods, teams try to make ends meet with small additions. The change of manager was important for Manchester United. They did that and we can say that the new manager has not adapted to the team yet. First of all, after he and his tactics are integrated into the team, we can watch a transfer period consisting of special players that he will choose in the summer. Maybe next year, Manchester United will compete for the Premier League championship.
Amorim needs time to adapt to Manchester United and Premier League style of play, and he will adapt soon, just that their fixtures are not friendly.
Manchester United have some set of big games they will hardly win, therefore, I expect United to still drop some points in their next three to four games.
