Callum McGregor believes Wilfried Nancy's desire to change 'too much too soon' caused his downfall as Celtic manager. Nancy lasted just 33 days, losing six of eight games, including a 3-1 defeat to Rangers. The captain says the drastic shift from the team's established 4-3-3 to a 3-4-3 system disrupted their rhythm.

Nancy's tenure was disastrous, with two missed chances to close the gap on Hearts at the top of the Scottish Premiership. Celtic now trail the leaders by six points, though a winning run under interim boss Martin O'Neill has kept them in the title conversation. The squad is drawing a line under the negativity.

Looking ahead, Celtic face Hearts on Sunday in a crucial league fixture. McGregor insists the players are focused on the future, not dwelling on past struggles. A victory would apply significant pressure on the league leaders and reaffirm the Hoops' title credentials despite their turbulent season.
