For me, the first targets would be two of Bissouma, Gravenberch, Gallagher and Kamara if VDB cements the DM role and we sign him. The midfield would be complete then...although i think we would only have enough funds for two players total with numerous outgoings.
Indeed he does. Id say Antony is the best player at Ajax now and the two of them could go on to be world class level.
Rebuilding the midfield can be a minefield of bad decisions and wasted money. There is no better case than Everton for that.
We had Gana which means you had to have very specific types of mids to make the whole midfield effective for the rest. Same would be for Kamara. If you throw a 10 into that midfield - which is what they tried to do with Siguurdsson, Klassen, Rooney, Vlasic - you'd then need either a world class DM/CM who is great at distributing the ball and switching play, holding onto the ball under pressure in tights space and a significant presence in defence and in the boxes. We had Scneiderlin, then Gomes.
That's a lot of wasted money and a lot of [Poor language removed] football.
If you don't go the 10 route you need two no.8s each side, both of which need to be able to drop and distribute at different times. Both needs to be good dribblers, good passers to link play and possess the vision to able to do that. So if we just get Kamara (and don't get Donnie) we're back to where we were with all that money spent and a lot more money needed to make the Kamara transfer worth the trouble.
Sure we've now got Ali to go the 10 route, but even with a world class DM/CM, Ali is the rock we might perish on.
Further this type of midfield formation is being undone more regularly by opposition - its not solid enough to take on the best where your really relying on 2 CMs to be the main defenders for the side as well as being the ones to get the whole side attacking; how do you play through the pressure and come out with a platform to attack from when its too easy these day for sides too take those 2 out of the game - Southampton being a case in point.
For me a much wiser use of money is to find two or three 8s with the prerequisite that they are good midfield defenders.
You can be more specific from there. One type of 8 is Bissouma, McKennie.
The other type is more the Dutch 8 like VDB who is moving all over the field linking, or off the ball covering the lines and space. A player who would not be out of place filling in the backline as moving into AM.
One more of a dribbler, one more of a linker, but both good defenders.
The two 8s open up the option to play a player like Douglas Luiz in the middle and switch to a player like Ali when a tactical switch is needed. Ie the two 8s are able to quickly fill the roles central midfield defense with Ali on.
Luiz type players would be huge in helping fix the weak presence in the boxes and he's superb with his passing range at getting counters going and relieving pressure.
The spenders need to stop seeing who can they get in midfield and have some sort of a plan.
Gravenbach is a tricky one. Again he's the sort of player that determines who the other midfielders will be.
He'd be better going to Italy and working on his defensive side to become the great all round player he could be.
At Everton a player like Gravenbach could be a disaster for both parties. Look at the problems Pogba has bought to United and multiply.
