Celtic are reportedly interested in signing former Crystal Palace midfielder James McCarthy.
According to the Daily Mail, Ange Postecoglou is in the market for a goalkeeper, right-back, central midfielder and winger this summer.
The 30-year-old midfielder has been identified as a target and may well be interested in joining the Hoops.
The boyhood Celtic fan is currently a free agent after leaving Palace earlier in the summer and could be a quality addition.
The 43-cap Republic of Ireland international’s signing should be a no-brainer, especially on a free transfer, and Celtic will be keen to seal a deal as soon as possible.
