Steven Gerrard deserves time to get it right.Few Old Firm managers survive back-to-back trophyless seasons but former Celtic boss O’Neill insists Gerrard must be cut some slack given Rangers’ recent history.The former Liverpool captain oversaw a competitive opening half of the season and ended 2019 with Rangers’ first win at Celtic Park since 2010.It meant that the teams headed into the winter break with Celtic just two points ahead of Rangers, who had a game in hand.A catastrophic collapse after the break meant that Neil Lennon’s side were 13 points clear when the league was called prematurely following the Covid-19 outbreak.
