Rangers 1-5 Celtic: Brendan Rodgers' undefeated Hoops outclass hapless Teddy Bears at Ibrox
Celtic dished out one last humiliation to hapless Rangers as their 5-1 win at Ibrox took them to within five games of an unbeaten domestic campaign.
The Parkhead faithful lapped up every moment of this season's sixth and final Old Firm duel as Brendan Rodgers' undefeated troops outclassed a feeble Rangers line-up from start to finish.
Early goals from Scott Sinclair and Leigh Griffiths robbed the hosts of any belief they had left before Callum McGregor, Dedryck Boyata and Mikael Lustig's second-half strikes handed Celtic their biggest ever Ibrox win. Kenny Miller's late reply was no consolation.
While Rangers' hopes of finishing second are all but gone, their old rivals now need only negotiate their final four league games and the William Hill Scottish Cup final against Aberdeen to complete a loss-free league season and historic treble.
Despite boss Pedro Caixinha adding the attacking intent of Josh Windass and Joe Dodoo and the defensive experience of veteran Clint Hill to his team, there was no real resistance.
Such were the confidence levels among the away supporters, they even cheered as the home team was read out.
Rangers needed to avoid going behind early - but they lasted just seven minutes before conceding.
Myles Beerman was again starting at left-back for Caixinha's team but the 18-year-old's inexperience showed as he needlessly dived on Patrick Roberts inside the box.
Referee John Beaton consulted linesman Alan Mulvanny before pointing to spot, with Sinclair then sending Wes Foderingham the wrong way.
Frustrations were already boiling over in the stands and they erupted in appalling fashion as the champions wheeled away to celebrate, with a Rangers fan leaping from the Govan Stand to confront Celtic skipper Scott Brown.
Beaton and James Tavernier had to restrain the intruder before he was removed by police.
Brown was almost in trouble himself after catching Miller with an elbow, but he got away with a talking-to.
However, things would only get worse for Rangers as they found it impossible to stop their rivals flooding forward. While the hosts' passing was erratic, Celtic's exchanges seemed laser-guided.
And they struck again after 18 minutes. Stuart Armstrong robbed Emerson Hyndman in midfield before spraying the ball forward to Griffiths, with the striker - only starting because of Moussa Dembele's hamstring injury - ripping a sensational drive past Foderingham.
Rangers were left stunned when Beaton refused to give a foul after Jozo Simunovic careered into Miller, but Celtic did not hang about and only the crossbar denied Griffiths again. Sinclair put the rebound wide then missed an easier chance at the back post on the half-hour mark.
That Rangers reached the interval just two goals down seemed a minor miracle. Their only two attempts in goal during the entire half from Windass and Miller both failed to test Craig Gordon.
Caixinha looked to stiffen up his midfield by swapping the anonymous Dodoo for Andy Halliday.
But the tide continued to flow in one direction only and it took Celtic just six minutes from the restart to stretch their advantage.
Rangers surrendered possession again and McGregor made them pay as he netted by drilling the ball through Tavernier's legs and into the net from 12 yards out.
But when Boyata was allowed to jump unchecked from a Griffiths free-kick on 66 minutes, that was the cue for the Rangers faithful to head for the exits.
Miller did beat Gordon with 10 minutes left after swapping passes with Joe Garner, but even then Celtic did not relent and Lustig wrapped up Celtic's second five-goal derby display of the season when he ghosted through a non-existent Rangers defence to slot home at the death.A Twitter List by BelTel
My Bhoys are set to pounce, says Brendan Rodgers
Brendan Rodgers believes Rangers could play into Celtic's hands if they loosen the shackles in today's Ladbrokes Premiership encounter at Ibrox.
The Light Blues were criticised for their reticence, especially in the first half, of last Sunday's Scottish Cup semi-final defeat at Hampden where the Hoops coasted to a 2-0 victory.
The pressure is on Rangers and their boss Pedro Caixinha to take the game to Celtic this time to look for their first Old Firm win in six encounters this season.
That expectation was noted by Hoops boss Rodgers, whose side are unbeaten domestically this season and on course for the treble.
The Ulsterman said: "It is their home game and they will look to maybe press the game a little bit more.
"But it is always difficult and if they do decide to press more then it can be even better for us.
"It will open up the space behind the pressing line, a big space and we have got speed in our team.
"But we will prepare as we normally do for a tough game. We played very, very well on Sunday.
"The only disappointment was the scoreline didn't really reflect the dominance of the game.
Rodgers continued: "We will respect the opponent which we always do but really look to impose our style on the game."
Celtic are unbeaten in five Old Firm matches this season including a 2-1 win at Ibrox in December.
The former Swansea and Liverpool boss has no problems with another one arriving so soon.
"It is one of the world's great derby games," said Rodgers, who will have striker Moussa Dembele missing through injury but skipper Scott Brown available after his recent red card at Ross County was reduced to yellow on appeal.
"They normally don't come around that fast but we always look forward to it. Our game at Ibrox last time, there was a great atmosphere with both sets of supporters, it was a good game and we came out on top.
"We are planning to win the game, that's how we go into every game. These games are never comfortable. They are always tough games, they are always competitive."
Meanwhile, Rodgers insists Patrick Roberts' best interests will be central in discussions about his club versus country dilemma.
The Hoops attacker, on loan from Manchester City, is a key part of England's Under-20 squad who are looking forward to the forthcoming Under-20 World Cup.
However, the South Korean tournament clashes with the Scottish Cup final at Hampden Park on May 27, where Celtic will look to complete the domestic treble when they take on Aberdeen.
It was reported that Fifa had confirmed that England do not have the final decision over the 20-year-old's availability.
However, Rodgers said: "England announce their squad in May and I am sure there will be a discussion. We want him to be here so we will see how that goes. It will be a sensible claim.
"He is here on loan, but we respect the people at England, we will have a conversation about it and hopefully it will fulfil the needs of both parties.
"Pat knows there is a World Cup opportunity there for him, he has worked hard to be there. It is unfair to put the boy in that situation really. He has played a big part in what we have been doing.
"I am sure between City, England and ourselves we will come up with the best solution in the best interests of Pat."
