According to Post reporter Chris Wheeler, another reason why Manchester United did not sign Martin is that Sancho is unwilling to transfer to Villa permanently.
The reporter wrote: "One reason why Manchester United chose Ramens over Martinez is because Sancho is unwilling to transfer to Aston Villa permanently. Martinez's high salary means that Manchester United must charge transfer fees for Sancho, but Sancho is more inclined to rent."
"Sancho's loan has no rental fees, but Villa needs to pay at least 80% of the salary. If the bonus conditions are met, the maximum full salary will be paid."
