Black Eagles play Group leader Porto

Besiktas Black Eagles takes on Porto tonight in the Champions League Group Stage match away at Portugal's Dragao Stadium in Porto.

Porto leads the Group A with eight points, followed by Marseille and Liverpool with seven and Besiktas with four.

Tonights other match, Liverpool Reds is hoping to rely on its history of comebacks to reach the second round of the Champions League.

The five-time European champion needs a win at Marseille tonight to advance and avoid watching scoreboards for help.

The Reds started the group stage with a draw, then lost to Marseille at Anfield and at Besiktas. But since, Liverpool has rallied to win its last two and is hopeful to keep the momentum going in the final group game.

''If you'd told me five minutes after the final whistle against Marseille at Anfield we'd go into the last game knowing a win would secure our qualification, I'd have bitten your hand off at that offer,'' Liverpool captain Steven Gerrard said.

''It was even worse when we lost to Besiktas. We knew then we had a real uphill struggle, but after our recent performances in the competition, we know it's up to ourselves again.''

Liverpool rallied from 3-0 deficit to beat AC Milan and win the 2005 European Cup on penalty kicks. On its way to reaching that final, Liverpool rallied to a 3-1 win over Olympiacos in its last group game, which pushed the club through to the last 16.

Liverpool also reached last season's final, which it lost to Milan 2-1.

A draw will only be good enough for Liverpool if Besiktas beats Porto in the other Group A game.

Defending champion AC Milan already has advanced, along with former winners FC Barcelona, Manchester United, Celtic and Inter Milan and Arsenal, Sevilla, Chelsea and AS Roma.

Along with Liverpool, other European heavyweights also have yet to clinch their places.

Nine-time winner Real Madrid needs a win over Lazio tonight to be sure of a place from Group C.

Madrid and Olympiacos both have eight points, followed by Werder Bremen with six and Lazio with five. Olympiacos hosts Bremen.

Bremen and Lazio could still qualify if they win their matches.

Rosenborg is in the best position to join Chelsea from Group B. It plays at Schalke. Rosenborg has seven points, followed by Schalke with five and Valencia with four.

Schalke will reach the next stage with a win against Rosenborg, anything less would eliminate the Bundesliga champion from European competition altogether if Valencia beats Chelsea at Stamford Bridge.
