No way United will make only the 3 signings, the transfer business this window will be both a reaction to last season's 19 point deficit and those player's who will leave like Darmian, Blind, Feillani, Rojo or Jones, Mata or Herrera, Carrick, Zlatan (I think Shaw and maybe Martial will stay one more season) but Mata or Herrera will be sold to try and get the outgoings to 75M. Mata is on 180k so he would help free up the wage bill needed for a marquee signing!
The transfer Market is always moving, if Bale and his agent get no joy from Madrid, deciding to leave for United, PSG finally agree to sell Neymar to Real Madrid then United's strategy will change, therefore it should be assumed delays in any transfers are due to the board and Jose probably having two scenarios, Plan A and Plan B but Jose priority is to buy Wing Backs and at least 1 top centre Midfield player but you have to assume that Plan A includes a Bale, Griezmann, Ronaldo, Sergej Milinokovic Savic or Neymar and funds will be made available as a separate exceptional acquisition to the club.
PLAN A
Bale, Griezmann, Dyballa, Neymar (in that order of likleness to happen) - 120M
Sandro, D Rose, K Tierney, J Alba, D Alaba - 40M
Fred, Sergej Milinokovic Savic, Jorginho, Wegl - 53M
Toby Auderweild, L Bonnuci, J Boatang, Sokratis - 55M
Diago Dalot, Jao Cancelo, C Soares, T Meunier - 17M
The bold are the most likely options and the total cost would be 285M gross - 80M to 85M the club would generate in sales with fringe players like J Wilson and Sam Johnstone being sold plus a 50% sell on with Wilfred Zaha so probably 200M net spend. The two spurs players which we may end up with may also cost us Martial!
PLAN B
William, L Bailey, Goncalo Guedes, Thomas Le Mar
Sandro, Rose, Ghoulam, Guerrera, Betrand
Harry Maguire, James Tarkowski, Skrippier, L Bonnuci
Fred, Fabian Luiz, Arturo Vidal,
Mandzukic, Anoutivic, Dries Mertens, J Draxler
Diago Dalot, Jao Cancelo, C Soares, S Coleman
Plan B would probably cost £200M with 50M being regained in player sales with a net 150m spend.
There seems to be a real desire for the club to close the gap on City next season, so maybe by the time the window closes the United Squad will most likely feature a combination of both Plan A and B , rest assured we will certainly make more than just 3 signings!
