The outstanding matchups this weekend in European soccer.
SATURDAY
BARCELONA VS. ZARAGOZA
Rarely are a coach and his team so close in age, in experience and in shared success as Pep Guardiola and Barça. The 40-year-old coach completed his record of overseeing Barcelona victories on every ground in La Liga with Wednesday’s triumph at Valencia — the 81st win in Guardiola’s 102 matches as coach.
However, he ended the night in the hospital suffering a herniated disk in his lower back. And while Lionel Messi and Co. should routinely dispose of Zaragoza at Camp Nou, with or without Guardiola on the sideline, the team will need his guidance three days later to help overcome Arsenal in the Champions League.
Zaragoza has scored only seven goals, and one victory, on the road all season.
JUVENTUS VS. A.C. MILAN
Six defeats in 10 games has reduced Juventus to the sad role of a spoiler in the title race. Its last home win, against Inter, could prove decisive if Juve falls this weekend to A.C. Milan.
Milan’s decisive 3-0 defeat of Napoli during the week reinforced its lead atop Serie A. But Milan could have half its mind on its Champions League trip to Tottenham next Wednesday — in which case the Old Lady of Juventus might raise her game and score an upset.
Even so, Juve’s board has seen and heard enough. There will be changes next season, as well there should be, given midfielder Felipe Melo’s admission that the team hasn’t given its all lately.
HANNOVER VS. BAYERN MUNICH
Munich’s chief executive, Karl-Heinze Rummenigge, calls for calm, but the team’s losses in the league and the German Cup leave coach Louis van Gaal exposed. Win, lose or draw at Hanover — one of three clubs ahead of it in the Bundesliga table — Munich’s season will be a disaster unless it wins the Champions League. ‘‘We have thrown away our entire season,’’ admits Bayern’s young midfielder, Thomas Muller.
SUNDAY
LIVERPOOL VS. MANCHESTER UTD.
Old adversaries, and old enmities, collide at Anfield on Sunday. Manager Kenny Dalglish’s return to Liverpool rekindles his 20-year rivalry with Sir Alex Ferguson, a fellow Scot. The clubs barely need personal rivalries to stir their juices, however, and Liverpool will do everything in its power to prevent United from winning another English title.
For United, wounded by the loss through injuries and suspension of three, perhaps four key defenders, there is always Ryan Giggs. He has now passed Bobby Charlton’s record of 606 league appearances for the team, and signed a new contract to extend his run into his 38th year, and his 22nd as a top player.
Liverpool might field its new $56 million striker, Andy Carroll, though Dalglish refuses to give Ferguson the knowledge of whether Carroll starts or is on the bench. ‘‘He’s done everything the medical people asked of him,’’ Dalglish said. ‘‘Whether Andy will be involved on Sunday, I’m sure Fergie would love to know.’’
SANTANDER VS. REAL MADRID
After its 7-0 romp against an acquiescent Málaga on Thursday, Madrid faces sterner stuff at Santander. The Málaga coach, Manuel Pellegrini, virtually admitted his team gave up Thursday’s match before the kickoff, but Santander, undefeated in six games since it changed owners and changed coaches this year, will have more backbone.
Real waits to see if Cristiano Ronaldo is fit after he tweaked a thigh muscle shooting his third goal against Málaga.
MARSEILLE VS. LILLE
Might this be Lille’s last weekend atop the French league? Its five-point lead disappeared over two games, and Marseille, the champion last season, is grinding out victories despite injuries to strikers André-Pierre Cignac and Loïc Rémy and winger Mathieu Valbuena.
‘‘We’ll need to be strong because we’re going to suffer a lot,’’ Lille midfielder Florent Balmont said. ‘‘If we get a point, we’ll be happy. But we must not go there faint-hearted.’’
