Celtic swept Rangers away with an emphatic second-half performance to record their first Ibrox success in seven years.

Lubo Moravcik netted a sweetly-converted double before Henrik Larsson notched his 50th goal of the season late on.

It was also Rangers' third successive home defeat and further proof of how much Celtic have dominated Scottish football this season.

For Rangers all there remains after this humiliation on their own patch is the picking up of another point to confirm Champions League football next season.

Celtic can now look forward to clinching the Treble by lifting the Scottish Cup safe in the knowledge that every other task, apart from one amazing, irrelevant blip at Ibrox earlier in the season, had been achieved.

The match kicked off at a frantic pace and there were some hefty challenges from the off.

One came from Craig Moore, which was perfectly timed on Tommy Johnson, but Barry Ferguson's subsequent challenge on Alan Thompson earned him a yellow card.

The early pressure came from the home side with Jorg Albertz eager to let fly from distance although he rarely found the target.

Ferguson then almost opened the scoring with an impressive strike in the 21st minute after Paul Lambert lost possession in midfield, but his chip over Rab Douglas just cleared the crossbar.

Rangers came even closer from their next attack, but Rod Wallace headed wide of the far post from right in front of the goal.

Celtic had struggled to create much from open play in the first half with Larsson not getting a sniff and Moravcik also quiet.

But it was the veteran Slovak who opened the scoring after Larsson had slipped it into his path on the edge of the ares.

Moravcik strode into the area and rolled a side-foot past Stefan Klos, who was unable to make what would have been his first real save of the afternoon.

That prompted two very different substitutions, with Rangers taking Konterman off and sending on play-maker Tugay.

Celtic replaced Johnson with 18-year-old Sean Maloney and he almost scored within two minutes of coming on.

Lennon's tackle on Amoruso set up a counter-attack that saw three Celtic men with just a single defender facing them and Larsson set up the youngster, but his finish was straight at Klos.

Then Douglas hoofed the ball downfield, Maloney headed on and Moravcik sent the away fans ecstatic by turning Ricksen in the box and stroking the second past Klos.

Rangers tried to reply quickly but Tugay saw a shot blocked, and though the ball fell kindly for Flo in the box, his reactions were too slow and he was closed down.

Maloney almost scored again when Thompson found him unmarked at the far post but again Klos was in the way.

Moravcik's replacement, Jackie McNamara, set up Larsson for the killer third strike, the Swede rounding Klos and squeezing the ball in from a tight angle for his 50th goal of an amazing season.

Larsson almost made it four but with Moore closing him down he could only fire at Klos.
