I don't necessarily agree with all those needs.
1.The central midfield playmaker can come in the form of Eriksen. In addition, not every team has this type of player. We could get a box to box midfielder and that would work well too. In future I would like to sign one, but I wouldn't call it priority. We would also have the opportunity to test Zidane Iqbal, see whether he can come into that position in future to replace Eriksen.
2. Ball Playing Keeper - That would depend on our sale of both De Gea and Henderson. I think this can happen and I also think that due to the new profile of keeper, it would be accessible for way less than what some other keepers have cost. De Gea being as good as he is kinda taught how useless it is to spend that much money on a keeper, particularly when there are issues elsewhere.
3. Right Back - I do think we should get one. This season pretty much is a test for Dalot. I think he was good today and seemed good defensively as well. I would like to see what he ends up looking like.
4. Striker - The modern game is moving away from a specified no.9. It's a position that is really expensive and may not represent value in the market. We need the year to heavily scout the position because buying a Lukaku or Morata would cost us significantly. I personally would rather for us to pick up good attackers with good potential and have them compete with Martial/potential Memphis. That way, even if we don't get a 30 goal per season forward, we would have strikers in that position that could supplement each other to achieve even more than that number.
I say this because if you look through premier league history, most of the teams who have won the league have not had 20 league goals per season strikers in their teams. Our 93-95 team didn't. Our 1997 - 2001 team didn't. Arsenal's 98 team didn't. Chelsea's 04-06 team didn't. Chelsea's 14-15 team didn't. Both City's 14 and 18 teams didn't as well.
Additionally, we have Bruno Fernandes who I expect to chip in with a bunch. Rashford is also a goal scoring forward as well.
