Let's look at transfer activities of post Ronaldo seasons of SAF, DM season, LvG last season.
2014/2015 - Buy: 145.5m, Sell: 41.3m, Total spend: 104.2m, players still left: A. Herrera, L. Shaw, M. Rojo, Di Maria, D. Blind, V. Valdez
2013/2014 - Buy: 67.7m, Sell: 1m, Total spend: 66.7m, players still left: G. Varela, M. Fellaini, J. Mata
2012/2013 - Buy: 63m, Sell: 11.9m, Total spend: 51.1m, players still left: N. Powell
2011/2012 - Buy: 52.9m, Sell: 14.75m, Total spend: 38.15m, players still left: De Gea, P. Jones, A. Young
2010/2011 - Buy: 27.2m, Sell: 13.65m, Total spend: 13.55m, players still left: C. Smailing, J. Hernandez, A. Lindegaard
2009/2010 - Buy: 21m, Sell: 85.5m, Total spend: -64.5m, players still left: A. Valencia
After Ronaldo left, we have addictional 64.5m to spend. SAF spent a total of 102.7m. 102.7m - 64.5m = 38.2m. SAF only spent 38.2m on his last 3 seasons!!! And that does not include the club earning. From this 38.2m, Smailing, Jones, Lindegaard, Young, De Gea still in Man Utd squad. And 22m of this 38.2m is also spending on RvP who won us title.
So I am making a theory here. SAF is saving the transfer war chest for upcoming Manager. He knew it will be hard for new mgr to takeover him. So he save the money to help the new mgr. Assume each season we have 50m warchest. In last season of SAF, he has at least 150m to spend.
To add on to what you said above.... remember what RVP said previously? That LVG was given 150 million to spend this summer? Now let's calculate the current purchase up to today....
All together, that's 76.1 spent. Now to add those sales so far...
Total sales is 8.95. Subtract the amount spent, and the total is 67.15 million. Therefore, for this summer... 150 million - 67.15 million = 82.85 million left to spend for LVG.
But then.... assuming last year LVG got 150 million to spend also last season, this means that...
.
So now, LVG actually have about 128 million left for spending at the moment. We can buy all these players - Ramos, Otamendi AND Kane / Cavani - and STILL don't need to even worry how much we have.
