Liverpool late show sinks Gunners

With seven minutes left, Arsenal looked like were through as the score stood at 2-2.

But Steven Gerrard became the first Liverpool player in history to score in four successive home European matches to send his side ahead again from the penalty spot, before Ryan Babel's breakaway goal sealed a victory which sets up another semi-final clash with Chelsea.

Arsenal scored first through Abou Diaby, before Sami Hyypia and then Fernando Torres forced Liverpool ahead. Another Adebayor strike with seven minutes left looked to have finished off the Anfield men.

But Gerrard's penalty and Babel's late break sealed another sensational night at Anfield.

The Liverpool supporters were stunned into silence as Alexander Hleb threaded a ball down the right for Diaby to surge into the box before crashing home a shot between Jose Reina and his near post.

But veteran defender Hyypia produced a towering header from Gerrard's corner that crashed into the net off Manuel Almunia's post on the half-hour.

And Spain striker forced Liverpool ahead after the break. Peter Crouch's flick-on reached the Liverpool goal machine in the box, he turned Philippe Senderos with ease before firing his shot into the top corner.

Adebayor missed when clean through, but Liverpool went searching for more goals, and Arsenal caught them cold on the break. Theo Walcott embarked on an amazing run from his own half before pulling the ball back for Adebayor to drill in the equaliser after 83 minutes.

But straight from the restart Babel surged into the box and was brought down by Kolo Toure. Swedish referee Peter Frojdfeldt pointed to the spot, and Gerrard drove the penalty high into the net. And with Arsenal chasing another equaliser, Babel made sure of Liverpool's place in the last four, driving home a glorious fourth.
