Barcelona maintained their 100% record in Champions League Group C with a 5-0 rout of hapless Basle on Wednesday.
Goals from Lionel Messi, Sergio Busquets, Bojan Krkic (two) and Xavi Hernandez saw the Catalans run up the joint highest away win in Champions League history.
It was the third successive defeat for Swiss side Basle while Barca remain at the top of the standings with a three-point lead over Sporting Lisbon, who were 1-0 winners over Shakhtar Donetsk.
The Ukrainian side dominated from start to finish, but they were made to pay for their inability to score when Liedson finished with Sporting's first shot on target after 75 minutes.

The Romanians were the orchestrators of their own demise as defender Ricardo Cadu turned the ball into his own net in the 53rd minute while Eugen Trica was sent off right at the death to cap off a miserable evening.
In Group B, Internazionale opened up a three-point cushion over Anorthosis Famagusta with a 1-0 success over the Cypriot side in Milan. Adriano scored just before half-time to help Inter collect all three points in what was a solid if uninspiring performance.
Hugo Almeida was the hero for Werder Bremen as he struck a late leveller to deny Panathinaikos a first Group B victory in a pulsating 2-2 draw at the OACA Spiros Louis Stadium.

The 29-year-old then made the game safe five minutes from time when he stooped to glance a header past OM goalkeeper Steve Mandanda following a right-wing cross from Edison Mendez.
