If the takeover process reaches an impasse and Man United still belongs to the Glazers, then Man United will have a bottleneck this season related to the lack of budget spent by Glazer. But if Sheikh Jassim succeeds in acquiring Man United, then most likely Man United will experience a very significant development.
This is somehow incorrect; Manchester United inability to spend this summer is not due to the Glazers but instead FFP restrictions; MUFC Need to make couple of sales to balance their FFP regulations or they spend only a little above 150M. Every summer, the Glazers spend good amount of money in the transfer market.
If the glazers remain, it would be nice if the owners set up a competent football head team to oversea signings, recruitment and contract talks; that way MUFC gets better
