Well my concern is this season so much has the echos of Mourinhos first season here. What appeared excellent transfer buys in his first window, actually playing some good football, high finish in the premiership and Europa league, all looking promising for the future though there was still a lot of deadwood, we really needed another cb, fb, dm, cf and wingers.
To be fair we went and spent a lot of money to strengthen the following summer to strengthen, so I hope this summer still follows suit. But I thought at the time then it was still a poor window. We got linked with lots of exciting players and then went and bought Lindelof (looked bang average at Benfica), Matic (decent signing, but there were lots of dm at the time we were linked with more exciting to me), Sanchez (ironically the one I was excited about) and Lukaku (such a Mourinho signing and never a United player, always gets goals but never been a fan, thought poor signing at the time, especially with the fee).
SHows that was a poor window when two of thos players are now gone already and now we really need a replacement in the first eleven for one of the others and competition/replacement for the other. ALso shows how right SOlkjears sentiment after Sevilla of wanting quality players not marquee signings as such is true.
ALthough a terrible transfer window for me is par for the coruse in terms of the number of ins/outs never being enough, we have spent a lot of money every season. The jury is still out on the last one gone as Fernandes/Maguire/James/Bissaka...that was a further £200m odd spent lets not forget. Bar James all good signings for me, though over spent by £50m for the £200m we probably should have got better players in . Mourinhos first with Pogba/Miki/Ibra/Bailly looked great at the time but hasnt really worked out beyond the actual season it happened.
For me, this summer hell even if we signed Messi or Sancho, if we dont make at LEAST three signings, its a poor window and whether the signings work out for us or not, if they are not quality, talented players we have also done very poorly as there are so many good players we can target this summer for virtually every problem position bar possibly right wing outside of Sancho, DM especially and I bet we dont even sign one
