That will certainly be the case with Nancy\u2019s three at the back system<\/a> and two-man midfield, as Celtic supporters wait for him to be appointed their new coach. <\/p>\n But from the current crop of Celtic players, how will they fare in a system many of them are not used to, because this isn\u2019t a road the champions of Scotland<\/a> usually go down? <\/p>\n Let\u2019s be honest, Callum McGregor hasn\u2019t been at his best<\/a> this season, and the midfield has probably been the biggest problem area before Martin O\u2019Neill\u2019s return<\/a>. <\/p>\n Speaking on Clyde 1, Ross McCormack<\/a> is worried about how Nancy\u2019s<\/a> two-man midfield, with three at the back, will harm a player like McGregor<\/a>.<\/p>\n The former striker doesn\u2019t think the Celtic captain, who turned 32 in June, now has the legs to play in a role that is more demanding than when he plays as a number six, with two number eights ahead of him. <\/p>\n \u201cDo you (Marvin Bartley) think, and you have obviously played against Celtic this year, Marvin, at Livingston (as a coach),\u201d said McCormack.<\/p>\n \u201cDo you think that, and I know Celtic have a lot of central midfield players, but does playing as a two suit many of them?\u00a0<\/p>\n \u201cI look at Callum McGregor this season. He probably looks as if he has lost a little bit of sharpness. Getting around the pitch. <\/p>\n \u201cSo, what happens then? If it isn\u2019t going to suit him. He is the club captain. You have to play him.\u201d <\/p>\n What is McGregor\u2019s best position for Celtic?<\/p>\n Bartley is part of David Martindale\u2019s coaching staff at newly-promoted Livingston, and he faced Celtic in August, losing 3-0, with McGregor coming off the bench. <\/p>\n![\"Callum](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2025\/11\/callum-mcgregor-after-celtics-defeat-against-braga-1759502118990-1024x576.jpg\")
