Revenge missions for Roma and Valencia

AS Roma will attempt to avenge a 7-1 defeat at Manchester United FC when they visit Old Trafford on Matchday 2 while Valencia CF and Chelsea FC meet again.

Flurry of goals
Roma's first trip to United last season proved a painful one as they surrendered a 2-1 advantage from the home leg of their quarter-final, going down under a flurry of goals against the soon-to-be English champions. With both sides having won their opening Group F ties, the Italian team will be determined to avoid another capitulation in their Tuesday encounter.

Lyon quest
On the same night, Olympique Lyonnais will look to secure their first Group E points at home against Rangers FC while FC Barcelona go to VfB Stuttgart. FC Internazionale Milano, meanwhile, will try to put their Matchday 1 reverse at Fenerbahçe SK behind them when they host PSV Eindhoven, and Sevilla FC will bid to open their Group H account against visiting SK Slavia Praha.

Mestalla trip
On Wednesday, Chelsea will travel to Valencia for their first UEFA Champions League outing under new manager Avraham Grant. The London club went to the Mestalla Stadium last term in the quarter-finals, winning 2-1 thanks to Michael Essien's late goal to progress 3-2 on aggregate. The Spanish side may think they have unfinished business with their Group B rivals.

Old scores
Celtic FC could feel the same way about European champions AC Milan, who eliminated them in the first knockout round last season, as they seek a first win in what will be their seventh game against the Rossoneri, in Group D. Liverpool FC, whom Milan beat in the final last May, entertain Olympique de Marseille, aiming to settle an old score having been ousted by the French club in the fourth round of the 2003/04 UEFA Cup.
