Monaco-Zenit St. Petersburg
Match of the day
Liverpool-Basel, Group B, Anfield, Liverpool
History appears to be repeating itself for Liverpool and Basel, with Tuesday's match stirring memories of 2002/03. That season, the Swiss side went into their matchday six meeting on eight points, one more than Liverpool, and both were vying to finish runners-up in their group behind Valencia. Real Madrid are the Spanish club in pole position this time around, and once again Basel need just a draw to condemn their English rivals to an early exit.
Desperate for victory, on the other hand, the Reds are currently struggling for goals, especially at home, with Saturday's 0-0 stalemate with Sunderland leaving them with a record of seven from seven Premier League contests at Anfield, whereas their opponents are riding high in Switzerland. Back in 2002, Basel raced into a 3-0 lead before Liverpool mounted a thrilling comeback to draw 3-3 – a result that nonetheless spelled elimination. That game took place in Basel, however, and Brendan Rodgers' men will be hoping the unique atmosphere of a high-stakes European night at Anfield can spur them on to success.
The first club to qualify with just six points when they advanced last season, Zenit have seven this time around but need to win at Monaco if they hope to continue in the competition. For their part, the Ligue 1 hopefuls will have to make do without their leader at the back, the suspended Ricardo Carvalho, but have never lost at home to a Russian team.
Surprisingly eliminated at the first hurdle last term, Juventus now require just a point to progress against an Atletico side already through to the next phase. The Serie A champions could even qualify with a defeat, providing that Olympiacos fail to overcome Malmo. Unbeaten in nine matches at their Juventus Stadium home, La Vecchia Signora will look to Carlos Tevez to spearhead their efforts after Massimiliano Allegri rested the influential forward during Friday's 0-0 draw with Fiorentina.
