Manager may have concerns over his group of five central defenders withstanding the demands of a long campaignManchester United’s central defender quintet of Leny Yoro, Ayden Heaven, Harry Maguire, Matthijs De Ligt and Lisandro Martínez: an ideal blend of youthful zest and experienced winners or a unit that may prove vulnerable and injury-prone across the long months of the campaign?In Yoro, Heaven, Maguire, De Ligt, and Martínez, Michael Carrick can talk of high potential and seasoned operators who will patrol the manager’s backline safely. Except it would be understandable if the 44-year-old privately has any concerns about the five defenders, as a unit, especially as there is no plan to strengthen the position unless one (or more) departs.
