Steven Gerrard says it is time for VAR to be introduced north of the border after seeing Rangers' Betfred Cup hopes wrecked by Christopher Jullien's offside winner.
The Ibrox boss refused to blame Willie Collum and his officials as Celtic snatched a 1-0 victory at Hampden.
But after watching Jullien fire home from an offside position, he believes it is time Scotland's referees were given the same technological support as their colleagues in England.
Lennon said: "After he was sent off I just told him, 'You were outstanding son'. He maybe had to do it. I had no issue with the penalty decision or the red card. I thought up until then he was one of our best players.
"For a 18-year-old kid to play as well as that, he can be anything he wants to be.
"He's untested because he's so good. He takes players the other way. We see him every day in training against James Forrest, Jonny Hayes, Scott Sinclair, Lewis Morgan, Mikey Johnston and he can defend. We had no qualms about him playing today at all."
