United wants an unrealistic amount of cash and since Madrid is not willing to pay the idea is that the offer is disrespectful

.In the same contract situation Madrid paid 30m€ for Kroos, one of the best midfielders in the world. For being spaniard and to compensate the currency situation £-€ they might pay 35/40. De Gea wanted to renew but with a 30m€ release clause, what United didn't accept,so probably they already had in mind the "Van Gaal is upset/we are not selling" to try to get more money lengthening the situation, the Levy's methods. To keep a player against his will when there is an offer on the table is also unrealistic,maybe not in the mind of the fans but I guess that the club should be interested trying to get the investment back.
