He asked to leave, and United decided to sell rather than risk losing him for a lesser fee in the summer.
As his contract expired at the end of the season he was free to move on, although any side signing him would be forced to pay a transfer fee - set by a tribunal if no agreement could be reached between the two clubs - as he is under 24.
Following the sale we have been asking visitors to this site to tell us what they thought via our poll.
We asked if we got enough, with three options: No, yes, and "we shouldn't have sold".
35.1 per cent thought the money received, which will hit £850,000 if Wolves reach the Premiership and a cut of any future sale, was acceptable.
43.2 per cent felt that it wasn't, while 21.6 per cent - just over a fifth of voters - believed that the club should not have parted with Keogh.
