Very simple solution, simply TELL the Madrid controller that you must reduce speed, if it looks like the plot will not work out and you are kept high. If you say nothing, how are they to know?
Has worked for me many times. If you should land long and overrun (for example), you could hardly tell the Board of Investigation that...the controller made me do it.
Speak up if you don't like the situation.
