The defender is out of contract in June and with City's defensive crisis, the Sky Blues are keen to take McPake, who has signed a pre-contract agreement as cover.
Chris Coleman has already said about bringing McPake in sooner rather than later: "It doesn't take a rocket scientist to look at our situation and see that we need a bit of help. So, with a bit of luck, if something can be done in the transfer window, then great."
About the defender, Coleman said: "We watched him a lot last year and then he played in the friendly between the clubs and did a very good job. I think he will be good for the Championship."
