Angel di Maria must demand a transfer if he wants to leave Manchester United.
The Daily Mail says United will only consider selling record signing Di Maria if the unsettled winger asks to leave the club.
The Argentinian has not proved to be value for money since his £60million transfer from Real Madrid last summer, scoring only four goals in a debut campaign that began promisingly but tailed off.
However, United manager Louis van Gaal is not keen to write the 27-year-old off just yet and believes he can be integrated in to United system if he gets a decent pre-season under his belt after this summer's Copa America tournament in Chile.
