Madrid: Lionel Messi and Cristiano Ronaldo's record goalscoring form looms as the decisive factor when Spanish league leader Real Madrid play at Barcelona on Saturday in a crucial "clasico" that will effectively determine the destiny of the title.
Real have seen a 10-point lead over three-time defending champions Barcelona whittled down to just four points over the past month, and a loss at the Camp Nou would see the advantage sliced to just one point with four more games remaining.
Real may be the hunted, but of the two teams, it is Barcelona that can least afford to lose. Coach Pep Guardiola, who has only lost once in 10 games against Real, said "if they win [the league] is over."
Ronaldo's 41st goal of the season — and 53rd overall — last weekend saw the Portugal forward surpass his record mark of 40 goals set last season. Messi, not to be outdone, scored a pair nearly two hours later to match Ronaldo and take his overall tally to 63, the best since Bayern Munich's Gerd Mueller scored 67 during the 1972-73 season.
Both players, and both teams, will be looking to recover from sub-par European performances in midweek. Real lost 2-1 at Bayern while Barcelona was beaten 1-0 at Chelsea in the first legs of their Champions League semi-finals.
In head-to-head duels dating to Ronaldo's time with Manchester United, Messi has scored seven goals to Ronaldo's five, while the Argentina forward has struck 10 goals in his past 14 meetings against Real.
"Leo Messi and Cristiano Ronaldo feed off each other, they are apart from everyone else," Guardiola said. "We're lucky to be afforded the chance to enjoy some great football players. They are decisive players. They score goals when the team is playing well or when the team is playing poorly."
Real can set a new mark for goals scored in a season by netting against their Catalan rivals. Last weekend, they matched they own record total of 107 goals scored during the 1989-90 season.
Jose Mourinho's tactics will be a key to the game. The Real coach may opt for a conservative approach knowing a draw will go a long way towards securing the title. But that tactic has always failed against Barcelona in a series of ill-tempered and acrimonious games.
Mourinho opted for a defensive display in a 2-1 Copa del Rey loss in January that left him under pressure from a usually staunch section of supporters. In the return leg, Mourinho unleashed all of his talented forwards, including Kaka and Mesut Oezil, and Real were unlucky to only draw 2-2 in a rare match in which Barcelona were outplayed on their home ground.
Kaka did not feature in Wednesday's loss at Bayern, when Mourinho went conservative again. Madrid's trio of Ronaldo, Karim Benzema and Gonzalo Higuain have combined for 107 goals in all competitions this season.
Both teams are expected to have fully fit squads available for a match that slips in between Champions League semifinals.
"The clasico will be very important but not definitive," Barcelona goalkeeper Victor Valdes said. "If we beat them we can't start believing we are champions."
Racing Santander could become the first club to be relegated if they lose to Athletic Bilbao and both Granada and Villarreal win their games. That would also cause problems for second-bottom Sporting Gijon, which play Rayo Vallecano.
Also, it's: Mallorca vs. Zaragoza; Sevilla vs. Levante; Granada vs. Getafe; Real Sociedad vs. Villarreal; Atletico Madrid vs. Espanyol; Valencia vs. Real Betis; and Osasuna vs. Malaga.
