Does that mean United are actually paying most of his wages, but a loan fee provides potentially a similar amount to the wages. Many loan deals a complex but a simple one would see the destination club paying the player's wages and loan fee to the origin club (to contribute towards tranfer repayments/loyalty bonus etc). So nitid are effectively subsidising the deal? Sorry if being a bit stupidYet the BBC say Dortmund are paying all his wages, as if they could pay 350K a week but typical BBC spin on the loan fee:
Dortmund will pay 3.5m euros (£3m), with up to an additional 4m euros (£3.4m) in add-ons which are subject to appearances, Champions League progress and qualification.
The deal covers the majority of Sancho's wages, and if the bonuses are paid in full it would be more than 100% of Sancho's salary to the end of the season.
