LONDON — Belarussian side BATE Borisov caused one of the biggest shocks ever seen in the Champions League when it stunned last season's beaten finalist Bayern Munich 3-1 Tuesday. The other likely title contenders all won with European champion Chelsea easily beating FC Nordsjaelland 4-0 away, while Barcelona saw off Benfica 2-0 in Lisbon but lost Carles Puyol with a dislocated elbow before Sergio Busquets was sent off. Like Barca and BATE, Manchester United maintained its perfect start with a come-from-behind 2-1 win over CFR Cluj in Romania where Robin van Persie scored both its goals. The game between Juventus and Shakhtar Donetsk, both regarded as dark horses in this season's Champions League, finished 1-1 in Turin where the Italian side chalked up a European competition record of eight successive draws. There were a win for Valencia, which beat Lille 2-0 to condemn the French side to a second successive defeat, while Celtic ended a run of 20 Champions League away matches without a win after a last-minute 3-2 triumph at Spartak Moscow. Braga, in contrast, maintained its fine European record on the road, winning 2-0 at Galatasaray to remain unbeaten in seven matches away from home. The biggest upset was in Minsk where BATE earned its first ever Champions League home victory as it beat a Bayern side which had won its last nine matches in all competitions. Goals from Aleksandr Pavlov, Vitali Rodionov and Renan Bressan gave the BATE a famous victory and all the Bavarians had to show for their efforts was a late Franck Ribery goal to pull the score back to 2-1 in the closing stages. However, the Belarus champion still had time to score again through Bressan deep into stoppage time. The victory took BATE to the top of Group F after it had recorded its first ever win in the competition by the same score against Lille two weeks ago. Valencia is level with Bayern on three points and Lille is bottom with none. Chelsea brushed aside the debutant of FC Nordsjaelland in Group E in Copenhagen with Juan Mata netting twice and David Luiz and Ramires also scoring. Chelsea keeper Petr Cech made an important save after 73 minutes when he turned a shot from Joshua John on to a post to preserve their lead. Minutes later Luiz scored from a free kick, prompting a defensive collapse from the Danish champion. Chelsea's win, and Juventus' draw with Shakhtar in Turin, left them top with four points, the same as the Ukrainians. Juve has two and the Danes are bottom with no points and no goals. Barcelona won Tuesday's Group G game against Benfica, though Puyol's injury has ruled him out of Sunday's ‘Clasico' with Real Madrid. Goals from Alexis Sanchez and Cesc Fabregas left the Catalans top with six points from their two games. Benfica has one point and Spartak none after the Russians held a 2-1 advantage against Celtic early in the second half before having Juan Insaurralde sent off in the 63rd minute which handed the initiative to the Scots. Gary Hooper gave Celtic the lead before Emmanuel Emenike scored twice to put Spartak in control. A Dmitry Kombarov own goal and a 90th minute header from Giorgios Samaras gave Celtic its first away win in UEFA's elite competition since a victory over Shamrock Rovers in the European Cup in 1986. United also came from behind to win at Cluj who took the lead after Pantelis Kapetanos capitalized on some poor defending after 14 minutes. Van Persie equalized with a goal that came off his head and shoulder 15 minutes later before scoring a sublime second with the outside of his left foot after 49 minutes. United tops Group H with six points, followed by Cluj and Braga on three and Galatasaray with none after a second successive defeat. — Reuters
