The match marked Luis Suarez's return to top flight football after being sidelined by 10-match ban incurred for biting Branislav Ivanovic last season.
Liverpool's goal machine made his comeback in style as he helped his team to victory by scoring two goals.
The first half was played in a frantic pace as both sides looked to attack with an early Martin Skrtel goal was ruled out for offside.
Sunderland came closest to goal when Sebastian Larsson rattled Mignolet's crossbar with a beautiful free kick.
Despite Sunderland's best efforts to match their opponents, it was Liverpool's Daniel Sturridge who scored their first goal in the 28th minute.
A free kick by Steven Gerrard was flicked on by Toure before being guided in by Daniel Sturridge's forearm.
Liverpool kept on attacking and they did not have to wait long as Suarez found the back of the net just eight minutes later.
Gerrard picked up Sturridge with a phenomenal crossfield pass and the striker drove at Kieran Westwood's near post, beating Carlos Cuellar with ease before providing a low pass in front of goal for Suarez to tap home.
The hosts uncharacteristically showed great spirit even after being two goals down and managed get a goal back within minutes after the restart as Giaccherini pounced onto a loose ball in front of goal after Mignolet had parried a long range effort by Ki Sung-Yeung.
The game then swung into balance as both sides looked to cut out each other and play in counter attacking mode.
The match continued with both teams coming close to goal on a number of occasions.
Victor Moses caught the eye for Liverpool as he played pivotal role in most their attacking moves. He came close on two attempts but was unable to find the net.
The game was hanging in the balance and with each passing minute Sunderland fans became more impatient.
Finally, the game was put beyond doubt by Suarez as he scored in the 89th minute to bring down despair for the home team at the Stadium Of Light.
