Barcelona have had a perfect start to their Champions League campaign so far this season, with two wins out of two. In those games they have scored five and are still yet to concede a goal. That puts them top of the group, although their opponent's today, Italian giants AC Milan, are just two points behind, and a win for the Italians today would see them leapfrog Barcelona to the top of Group H.

Milan have won one and drawn one game so far; defeating Scottish champs Celtic, but being held by Ajax to a draw.

Milan will have their work cut out tonight and will need a characteristic rock solid Italian defense tonight to keep out the attacking threat posed by Barca.

This match is the seventh time in three years these clubs have met in the Champions League, so they will be familiar with one another. Although Barcelona will be the clear favorites, they will have respect for their opponents today, and know that Milan have the ability to beat them if they are not at their best.

If Barcelona win today they will take a firm grip of the group, and would go 5 points clear of their nearest rival with just three games to go.

Milan are also struggling this season, securing just three Serie A wins in their 8 games to date.
