Alert display by the goalkeeper, whose decision-making and positionig was sound but he could do little to prevent Kalou's goal.
Hapless display by the left-back, who got destroyed by the pace and dynamism of Torres and Ramires on the right.
His lack of pace was frequently exposed by the speed of Chelsea's front four, and was torn apart by Torres for the goal. Came close to breaking the deadlock with a powerful second-half header.
Turned with the speed of an ocean liner and had to resort to illegal means to keep his head above water.
Made some excellent runs down the right in support and defended solidly.
Protected the defence with style and authority and his height was a valuable weapon at set-pieces.
If this was an audition for a Premier League move, he did not exactly pass it with flying colours. Looks like a colossus but did not play like one.
Seems to have been around forever, and looked it here, with an anonymous performance before being hauled off in the second half.
Flickered intermittently in the first half but came to life after the break with some high calibre runs and deliveries on the flanks.
Heavily involved but his distribution was hit-and-miss from the left.
The big No. 9 was a threat with his height and power but his finishing was wasteful.
Kept his concentration to make an outstanding close-range save from Jardel after 66 minutes.
Usually only seen in a tracksuit on matchdays but responded to his first Champions League start of the season with a solid display before bowing to cramp with 10 minutes left.
The strength and desire that the Chelsea skipper brings to overseas ordeals was prevalent in a commanding performance.
Masterful display that rekindled memories of one of his finest hours against Cristiano Ronaldo at the same arena. Fortunate not to concede an own goal in added time.
Goal-line clearance. Flying headers. Last-ditch blocks. Well-timed tackles. Is this the same David Luiz who has become a byword for unreliability in the Premier League?
The intensity of a third big game in six days looked to have caught up with the Chelsea playmaker, who looked rather leggy. Missed an open goal from a tight angle in the second half after rounding Artur.
J. Obi Mikel
One of those games when his calmness and leisurely style was a bonus rather than a hindrance.
Barracked by the home fans for his Porto connection, the midfielder responded with a passionate display that spilled over into some careless tackles. Came closest to breaking the deadlock in the first half with a stinging drive that was kept out at full grasp.
Outstanding energy and dynamism on the right flank as he showed his former club what they are missing. His pace caused problems to Benfica in the first half, and in the second he teamed up with Ferreira to quell the threat of Gaitan.
Given the nod over Daniel Sturridge, he responded with some selfless running on the left flank and slid in the crucial away goal following a clever run into the six-yard box.
Confident, lively and menacing. Worked the channels to great effect and set up the goal when he brushed aside Jardel, stayed on his feet and fed Kalou with a low cross. But the nearly-but-not-quite story continued inside the box with some wasteful finishes.
- 22 R. Turnbull
- 24 G. Cahill
Overlooked for Ferreira but helped Chelsea see out the last 10 minutes.
Helped Chelsea slow down the game late on after replacing Meireles.
- 5 M. Essien
An excellent late run should have been rewarded with a goal from Mata.
- 11 D. Drogba
