There can be no doubts about this team, who’ve earned all the credit they will ever need over the last three great seasons and one defeat can’t set them back.

Barça have a job on their hands to turn round the result from London, that’s true, but Wenger, Cesc and co know what Guardiola’s team can do at home and the memories of last year’s thrashing must still be fresh in their minds. 90 minutes at the Nou Camp can seem like an eternity when you are on the receiving end of one of Barça’s exhibitions and trying to hold onto a result.

If Barça can simply repeat the results they achieved in the Group stages against Panathinaikos, Copenhagen and Rubin, they will go through.

Panathinaikos feel backlash

The Greek team came to the Nou Camp just after Barça had suffered an unexpected defeat to Hercules and they were on the receiving end of Barça’s injured pride. Guardiola’s team ran out 5-1 winners as Messi, Villa, Pedro and Alves got the goals.

Win gives top spot

In game three of the Group, Barça saw off Copenhagen with two goals from Messi to take top spot.

Youngsters on song

With qualification ensured, Guardiola gave some of his fringe players a run out against Rubin and Fontàs, Bartra and Víctor Vázquez showed that the Club has real depth in talent, with Fontàs and Víctor Vázquez ensuring a 2-0 win.
