The former Rangers assistant manager believes that Morelos struggling to score goals after the mid-season winter break saw Steven Gerrard’s side’s Scottish Premiership title challenge fade away.
The Scottish Premiership title was called earlier this season due to the global health crisis, with the Hoops winning the championship on a points-per-game basis.
When the season was initially suspended, Neil Lennon’s side were as many as 13 points clear of second-placed and bitter Old Firm rivals Rangers, who had a game in hand.
“In my mind the thing that changed was Morelos stopped scoring. He went from scoring 25, 30 goals before Christmas, to one or two afterwards. That’s a big, big change in your game.
“Centre forwards at any level of football make or break your team. Odsonne Edouard scored all season for Celtic. He — and Leigh Griffiths coming in — made a difference.
“If your centre forward is not scoring then games become harder to win and if you’re not winning games, especially at Rangers, then it becomes difficult to win leagues.”
Morelos scored 12 goals in 26 Scottish Premiership matches for Rangers this season, according to WhoScored.
As for Edouard, the 22-year-old Frenchman scored 22 goals in 27 Scottish Premiership games for Celtic this campaign, according to WhoScored.
Celtic will be aiming to win their 10th successive Scottish Premiership title next season, and the Rangers players will have to be on top of their game to stop that from happening.
