The Colombia international was linked with a move away from Ibrox last month, but boss Steven Gerrard was adamant not even £50 million would have been enough to tempt Rangers into selling him.
The Gers will look to cash in on Morelos in the summer, though, with the striker eyeing a move to a bigger league.
It remains to be seen if suitors will be willing to part with anything close to £50 million for his signature, but a Rangers fans reckon he is worth £80 million if Celtic striker Odsonne Edouard is rated half of that.
