I think it depends on the extent of the clear out and numbers coming in to make real progress. This is the way I see it.
Replacing Carrick properly: Spending on a quality midfielder, his final season has been a non event. We will miss his experience but need somebody to take the burden over from an exhausted Matic.
Fellaini: If he leaves, looking likely but Jose clearly wants him to stay. I don't have a huge problem with the wig but I do how Jose sees him. The temptation to start him is an issue, he slows us down and should only ever be used as a plan b in the 75th minute. Need to replace with a forward thinking energetic player. He's almost in Jose's default setting, needs to stop.
Full backs: Shaw needs replaced, he clearly isn't fancied and it's time to move on. Young shouldn't be the first choice at Man United. He should be a squad player that is used rarely. Valencia needs competition and should be a squad player too, he's useful but we need a younger player with better delivery.
CB: This has been a strange season. Bailly has been injured too much and Rojo hasn't recovered from injury. Lindelof hasn't settled and we have been left with Jones and Smalling. One of the chuckle brothers needs to go. We can't have the 2011 defense of Valencia, Smalling, Jones, Young if we are serious about winning the league. I personally would like Smalling to be replaced, Jones is more injury proned but is the better player in my opinion.
Balance: Finding a way to get a settled midfield, getting the best out of Sanchez and Pogba.
Top teams away: We need to show more intent, I have no reason or problem with a draw at anfield but it's the manner. Fans don't want to see us camp outside our box. The fans need to see us take a game to a team away. Even a good counter performance like Arsenal. Not showing up to Spurs or Chelsea away just won't cut it anymore.
Less moaning from Jose: He has an effect on the players and feel around the club. Calling out players publicly and complaining about needing more after this window isn't acceptable. 3 summer windows should be enough to get what he needs in and out. Maybe more signings like Bailly is needed, rather than huge names at 70m plus. We need to clear out a few this Summer. Why are the club playing player's Blind, Darmian, Shaw ect when they aren't playing.
Games approach at Old Trafford: Starting with a high energy and not settling for a narrow victory. Fans want to be entertained. We don't want to settled for 1 or 2.0. We want intimidation and to be looking for a third and fourth, not protecting a lead to lesser opposition. We need to concentrate on what we can do, instead of nullifying and cancelling out opposition. That Sevilla game isn't man United, playing two defensive midfielders at home. The level of negativity should never be seen again in a knockout game. It's not acceptable, there is no shame in going out but you need to have a go and be brave. Jose will have no excuses next year, if he does it will only highlight his failure to deliver.
We have made progress but it's slow progress. Jose and the players have responsibility to perform. They are not the only one's either. Fans at Old Trafford need to show more support, stop sitting there mute and doing feck all. The club need to stop going in a merry go round of blame, need to address the issues or make a change next summer. It's time to improve and build on this season. Anything other than challenging for the league next year is a failure.
