Do or die for Liverpool in Atlético decider

Liverpool FC must overturn a one-goal first-leg deficit if they are to have a chance of reaching the inaugural UEFA Europa League final, having lost 1-0 to Club Atlético de Madrid in last week's tense semi-final opener.

• Diego Forlán bundled home the only goal of the match after nine minutes, and while Liverpool goalkeeper Pepe Reina said afterwards that the tie was now tilted "70-30 in Atlético's favour", the goalscorer said: "The goal is undoubtedly important but there are still 90 very difficult minutes ahead of us against an experienced team who will be at home."

Previous meetings
• The sides met for the first time in last season's UEFA Champions League group stage with both games ending in 1-1 draws, Simão scoring in the 83rd minute of the game in Spain after Robbie Keane had given Liverpool a 14th-minute lead.

• Liverpool went on to top Group D with 14 points and Atlético finished as runners-up on 12. Los Rojiblancos were knocked out by FC Porto on away goals in the last 16, while the Reds lost to Chelsea in the quarter-finals.

• The teams for the previous meeting at Anfield on 4 November 2008 were:
Liverpool: Reina, Agger, Keane (Ngog, 71), Gerrard, Riera (Babel, 61), Fabio Aurélio, Alonso, Arbeloa, Kuyt, Mascherano (Lucas, 77), Carragher.
Atlético: Franco, Antonio López, Pernía, Heitinga, Forlán (Agüero, 71), Raúl García, Maxi Rodríguez, Assunção, Maniche, Simão (Luis García, 90), Perea.

• Since that match, both John Heitinga and Maxi Rodríguez have moved to Merseyside, the former joining Everton and the latter Liverpool.

Match background
• Liverpool have lost the first leg of a UEFA competition tie 1-0 away from home on nine occasions, and have come through in all but one of those contests. Those overall triumphs include their 3-1 aggregate win against LOSC Lille Métropole in the last 16 of this season's competition.

• The only team to beat Liverpool after winning the first leg 1-0 at home were SL Benfica in the 2005/06 UEFA Champions League first knockout round, coming through 3-0 overall with Simão – now of Atlético – on the scoresheet at Anfield.

• Atlético have won the home opener of a two-legged tie 1-0 on eight occasions, going on to triumph overall five times. Two of those contests were semi-finals, with Los Colchoneros coming through against KFC Uerdingen 05 in the 1985/86 UEFA Cup Winners' Cup 4-2 on aggregate but going down to AFC Ajax in the 1970/71 European Cup after a 3-0 away defeat.

• Atlético have now played 18 games against English clubs, with the record W6 D8 L4 (W1 D4 L3 in England). That includes a 5-1 loss to Tottenham Hotspur FC in the 1962/63 UEFA Cup Winners' Cup final, which was held at Rotterdam's De Kuip stadium.

• Atlético's only victory on English soil came in the 1997/98 UEFA Cup first round, where they won 2-0 at Leicester City FC on 30 September 1997.

• Liverpool overcame Spanish opponents – Barcelona on both occasions – in the semi-finals of the 1975/76 and 2000/01 UEFA Cups. Both times, they went on to win the trophy.

• Liverpool have now played 29 games against Spanish sides in UEFA club competition with the record W12 D10 L7 (W3 D6 L4 at home).

• Those statistics include victories in two European finals; Liverpool beat Real Madrid CF 1-0 to win the 1980/81 European Champion Clubs' Cup and overcame Deportivo Alavés 5-4 with an extra-time golden goal in the 2000/01 UEFA Cup final.

• This is Atlético's 11th appearance in a major UEFA club competition semi-final and their first since they lost to Parma FC in the 1998/99 UEFA Cup last four. Those ten previous semis have produced four wins and six defeats.

• This is Liverpool's 15th major semi-final, with their most recent being a loss to Chelsea FC in the 2007/08 UEFA Champions League last four. Their 14 previous semis have ended in 11 wins and three defeats.

• Atlético have only won two games since the start of the UEFA Champions League group stage, drawing eight and losing three. They had drawn their last four matches prior to the first leg against Liverpool, progressing through the round of 16 and quarter-finals on away goals, drawing 2-2 away and 0-0 at home on both occasions.

• The 3-0 UEFA Champions League group-stage loss to FC Porto is Atlético's only defeat in their last 21 European fixtures at the Vicente Calderón. However, their first-leg victory against Liverpool was their first win in seven European home ties since beating Panathinaikos FC 2-0 in the UEFA Champions League play-off round on 25 August.
