The same cannot be said of Duran, who is thriving in a Celtic shirt and has 14 goal contributions – nine goals and five assists – in 15 games, many of which have come while playing in a wide role.
However, O’Neill has said that the Colombia international prefers to play centrally, and Halliday believes he can offer Celtic much more in that position – but what does that mean for Hogh?
“You look at Duran as a number nine on Sunday, the part he plays in the third goal, the fourth goal,” Halliday said.
“When Jamie McCart takes a loose touch, Hogh wouldn’t be close enough or quick enough to get on to that loose ball and spring Celtic into attack. Duran isn’t just a goalscorer, he’s so much more than that – and you saw that on Sunday.
“O’Neill still reckons Hogh will score 20 goals this season. It’s hard to suggest he wouldn’t, given his previous record at Bodo/Glimt, but at this moment in time, he isn’t doing enough to be in Celtic’s attack.
“O’Neill’s searching for his best team and best front three, and the three you saw on Sunday are that.”
