Stood no chance with Henderson's opener but produced a stunning stop to deny the Englishman and Luis Suarez in the second half.
Struggled with high balls and was not as attack-minded as Armero on the opposite wing. Liverpool should have seized the chance to attack him more.
Offered an attacking outlet down the left flank for his side but his final ball was often lacking. Good defensive performance though.
Dealt well on the whole with Suarez's runs in behind but had no particularly telling impact at either end of the pitch. Was sent off for two bookable offences after flooring Raheem Sterling late on.
A steady performance, but nothing spectacular. Failed to get himself into the game as Liverpool monopolised possession.
Was always in for a busy night marking Suarez and was often caught the wrong side of his man. Was pushed forward into a defensive midfield role in the second half.
Tricky and provided a handful for the Liverpool backline when exploiting the little pockets of space he was able to find, but was withdrawn at the break.
The game often passed him by as he struggled to assert himself in midfield, where Liverpool dominated. Improved in second half but had no real impact.
Posed a problem for Liverpool defence but was often clumsy when in possession and wasted glorious headed opportunities in both halves.
Unable to provide anything from his wide role in the opening period. Improved after the interval but a final ball was lacking.
Tricky and dangerous performance, came close to scoring the opener when he forced Pepe Reina into a good save from his delicate chip.
Made a wonderful first-half save and was generally alert but was inconsistent with his distribution.
Steady performance defensively from the marauding full-back but it was his attacking duties that impressed, went on several jinking runs without always having an end product.
Another wonderful performance from the revitalised Spaniard who proved his worth once more to Brendan Rodgers with a disciplined performance.
A fantastic performance from the Reds' defensive rock, who was always in the right position to deal with any crosses and runs from deep Udinese posed.
A reliable presence at the back and did not let his side down, dealing well with everything thrown at him. Was slightly at fault for Mathias Ranegie's first-half effort.
Took his goal nicely with an assured finish and showed good energy and drive throughout but was sometimes sloppy in possession.
Was forced off early with a nasty-looking nose injury and had no time to make any real contribution.
Neat and tidy in midfield as he kept his side ticking over. Offered little offensively but sat in front of his defence responsibly. An efficient performance.
Tried valiantly but was always on the periphery of the game and posed little attacking threat to the Italian side.
A tireless performance from the Uruguayan, who gave the home side a busy night's work with his constant movement. Was denied a goal by a stunning Padelli save.
A mixed night for the young Spaniard, who showed what he is all about with a number of slaloming runs and set up Henderson for the goal, but also wasted chances to double his side's lead.
