Reports have emerged today claiming that the Dutchman has told Welbeck that he is allowed to leave the club for pastures new.
However, it is believed that the 23-year-old will not be sold to a club who are likely to challenge for a top-six place in the Premier League.
When asked about the reports in this afternoon's press conference, Van Gaal said: "I know what I said to Danny Welbeck and he knows exactly what I said. I think the media is guessing."
The England international has been linked to Hull City and Sunderland within the last couple of weeks.
