图片报：为回归多特，桑乔愿意放弃目前一半薪水（图片报：桑乔为重返多特愿降薪50%）

Processing translation request

I need to handle the translation from Chinese to English. The text mentions that Sancho is willing to give up half his salary to return to Dortmund, so I can provide context about his salary at Manchester United, which is around £350k/week, implying a reduction to roughly £175k/week. It's important I don’t assert incorrect numbers. I’ll suggest options for the user, including a quick translation and background on the transfer situation. I’ll also offer a brief overview of the source’s reliability.
