Liverpool defeated domestic rivals Manchester City on penalties after a thrilling 2-2 draw in their International Champions Cup clash at the Yankee Stadium in New York.
Stevan Jovetic was the grateful recipient of the move that handed City a slender lead moments into the second half, prompting Jordan Henderson to produce a fine equaliser for Brendan Rodgers' side.
The Blues forward showed strength and composure to restore an advantage for his team three-quarters of the way into the clash, but the Reds levelled late on through Raheem Sterling.
That heralded a shoot-out to decide which team would take two more points in the tournament, with Lucas Leiva sending home the winner to secure a 3-1 win on spot-kicks.
Gael Clichy, operating from right-back, created the opening chance of the fixture on three minutes when he darted inside from the flank and careered into a central shooting position, only to scuff wide.
Jovetic was crowded out at the last moment after collecting a one-two from fellow forward Edin Dzeko, before the latter curled toward the far corner from the left edge of the area but merely found the waiting hands of Brad Jones.
In response, Philippe Coutinho was inches off target to the left with a daisy-cutter from 20 yards, having been picked out by a Jose Enrique centre at the wing that deceived the gathered City defenders in the middle.
Rickie Lambert was left to bemoan a lack of luck on the quarter-hour; Daniel Sturridge fed an onrushing Henderson to the side and the No.14's lofted cross to the back post was headed down by the England international, but Willy Caballero somehow blocked out.
Jones' reflexes were tested by a low Jesus Navas drive, Martin Kelly deflected away a James Milner hit and Bruno Zuculini should have done better than his eventual chip when released into space cleverly by Dzeko. When the Bosnian did find the back of the net shortly after, he was offside.
Kelly was again in the right place at the right time to deny the influential Dzeko, who had been found 10 yards out by Navas. Jones was briefly troubled but ultimately in control when the City striker saw yet another effort deflected high into the air.
Jack Robinson for Liverpool and Joe Hart were among numerous substitutes introduced for the second period and the latter was rapidly off his line in the 50th minute to thwart the former, who poked at goal from a narrow angle after collecting Sturridge's pass.
And three minutes later, City struck. Navas raced along the right touchline - his pace having proven a crucial feature of the encounter - and squared to cause a scramble that concluded with Jovetic forcing home to earn Manuel Pellegrini's team an advantage.
There was almost an immediate riposte when a Steven Gerrard pass fortunately diverted to Coutinho, but the Brazilian's finish was brilliantly stopped by Hart. Sturridge glanced over from the resultant corner.
Nobody could stop Henderson as the hour mark approached, however. Sterling looked for Sturridge and when the ball ran loose, the midfielder made no mistake by curling perfectly past the stretch of Hart and into the top corner for 1-1.
As the pace quickened, Aleksandar Kolarov seemed to have presented Zuculini with a perfect chance to grasp command back for City. Free at the far post, six yards out, the attacker contrived to crash his shot against the crossbar.
With 67 minutes on the clock, they made amends. Jovetic scurried forward, fed Navas wide and when the delivery found its way into the box, the Montenegro international held off the attention of Sebastian Coates to toe-poke underneath Simon Mignolet.
With five minutes remaining, though, Liverpool hauled themselves level. A pull-back to the edge of the area was expertly knocked around the opposition defence by Lucas for Sterling to sprint in and side-foot around Hart, paving the way for penalties.
City missed three of their four attempts, while Emre Can, Henderson and Lucas all converted to hand the Reds top spot and control of the group ahead of Saturday's meeting with AC Milan.
