Rangers boss Steven Gerrard lapped up a fourth Old Firm win of the season and it was especially sweet after suffering Scottish Cup pain against St Johnstone.
The Ibrox gaffer spent 72 hours plotting the Parkhead side’s downfall and he was thrilled his plan came together.
Gerrard said: “Seven days ago I was sitting here really stung and hurt as we’d missed a big opportunity but in terms of the league I can’t ask for any more.
“The consistency levels have been incredible.
“We’ve completely flipped the mood and we thoroughly deserved the win. We scored four really good goals and were a threat throughout.
“We worked on this game plan for three days. That’s not a long time.
“ Celtic are a good team but, with all due respect, there are weaknesses, especially in the backline. I wanted to put two men right up against those centre-halves and cause them problems and for Ryan Kent to continue to do what he does to Scott Brown, which is being a right menace.
“We needed Kemar, Alfredo and Ryan to be the difference for us in the final third and we ran away with it in the end.
“I’m really pleased with the performance. We started the game really well and picked a really aggressive and bold shape today as we wanted to go for Celtic’s throat.
“We did that and took the lead but unfortunately we were sloppy in terms of the equaliser.
“Then again it was us forcing the issue and Alfredo scored a fantastic second. There was also a big moment with the red card but it was the right call.”
Gerrard’s only downside was the second-half injury to Borna Barisic.
He said: “We’ll scan that in the coming days. We’ve got 10 days now until the next game and hopefully that helps.
“If Borna is ruled out, it could be down to six subs.”
Roofe stole the show but Gerrard was delighted defender Jack Simpson strolled though his baptism of fire.
He said: “It was his first start in a game of this magnitude for us. We trusted he could do it. He had a couple of moments within the game.
“We will analyse his performance and so will he, because he’s a kid who wants to get better.
“He did a lot well. He was up against one of the best players in the league in Odsonne Edouard, who gets assisted by Moi Elyounoussi and David Turnbull.”
