Sports??understands the 50-year-old will take control of United???s final 16 matches of the campaign, and the club are expected to make a formal statement confirming the appointment later on Monday.
Carver is still searching for his first win since taking over from Alan Pardew at the beginning of January, having overseen one draw and three defeats.
Speaking last week United managing director Lee Charnley ??? one of those tasked with finding Pardew???s replacement ??? admitted that the process might take some time.
???Clearly my preference is to try to find someone to bring in now,??? he said. ???However, if I have to wait until the summer for what I believe is the right individual, then I would rather wait.”
