Europe's elite club competition returns on Tuesday after a two-month hiatus, with 16 teams left standing after a typically tough group stage. The likes of Valencia, PSV Eindhoven, Werder Bremen and Lazio all failed to advance to the UEFA Champions League knockout rounds, leaving it to a clutch of familiar faces and one or two intriguing underdogs to battle it out for a spot in the quarter-finals.

Defending champions AC Milan are there, as are Liverpool, the team they defeated in last year's final, while the winners of the 2006 edition, Barcelona, remain firmly in contention along with Spanish compatriots Sevilla and Real Madrid.

All five of these clubs boast considerable pedigree over recent seasons, but perhaps you fancy Italy's ultra-consistent league leaders, Inter Milan, or one of England's top three - Arsenal, Manchester United or Chelsea - to claim the most coveted prize in European club football. It will be interesting, too, with Celtic, Olympiacos, Schalke, Fenerbahce and Porto themselves still in the race, to discover whether any users are willing to tip one of of these outsiders to 'do a Porto' by heading off teams from the continent's big five leagues.
