The result was an unfair reflection on aLiverpool side, who, had they taken their chances when in the ascendancy, might well have been in a position to take something from the game.

The rout sees Sporting finish top of Group 2 with 16 points from a possible 18, ahead of Liverpool in the second qualifying spot on 7points, having drawn one and lost three of their six fixtures.
With both teams having already qualified for the knock out stages and with the pressure off, the stage was set for an evening of open, attacking football.
Having been soundly dispatched 3-0 at Anfield in the tournament's inaugural game by Sporting, Liverpool came into the match looking to get a measure of revenge against the much fancied Portuguese.
The Reds named an attacking line-up with Raheem Sterling, Adam Morgan, Krisztian Adorjan and Micheal Ngoo all starting for the visitors.
The game started brightly, with both teams looking to attack down the flanks, Armindo Benena and Michael Ngoo looking particularly threatening for Sporting and Liverpool respectively.
Sporting went closest in the opening exchanges, and came close to breaking the deadlock on the quarter hour mark, Alberto Coelho only millimetres from making contact with a Mickael Pinto cross with the goal gaping.
The hosts didn't have to wait much longer for get on the scoresheet, taking the lead in the 19th minute with a clever set piece,
Edgar Ie smashing Alerto Coelho's short free kick low through the Liverpool wall and past a helpless Tyrell Belford.
Liverpool could have been level moments later, with Michael Ngoo the architect, the 19 year-olds powerful running proving to be a constant threat to the Sporting back four and having got the better of full back Ricardo Esgaio, his cut back found Connor Coady, but the Liverpool captain could only steer his shot narrowly wide of Sporting keeper Rafael Veloso's left hand post.
With both sides looking dangerous in an increasingly open first half, the threat of more goals seemed inevitable, Raheem Sterling forcing a fine point blank save from Veloso before the hosts extended their lead ten minutes before the break, Mickael Pinto crossing for Carlos Chaby to finish smartly .
The goal was harsh on a Liverpool side who had more than matched their opponents for long periods and they deservedly clawed themselves back into the fixture in the 39th minute, Michael Ngoo getting the goal his performance deserved, making the most of a Tiago Ilori slip in the Sporting area to smash home a Sterling cross to reduce the deficit.
Liverpool's hopes of a resurgence took a massive blow early in the second half with Alberto Coelho scoring arguably the goal of the tournament so far with an overhead kick you only tend to see on end-of-season highlight reels.
Coehlo and Medeiros would combine again on 61 minutes to devastating effect to put the result beyond doubt, Medieros again cross for the Sporting No 9 to score his 6th of the tournament from close range and knock the resistance out of a brave Liverpool side.
Sporting added a fifth on 86 minutes, substitute Gael Etock, having only been on the pitch for 3 minutes, rubbing salt into Liverpool's wounds with an exuberant 20-yard lob over Tyrell Belford.
