Promoted Alaves dealt champion Barcelona a shock 2-1 defeat at the Nou Camp Saturday while Cristiano Ronaldo returned from injury to help Real Madrid thrash Osasuna 5-2 and go two points clear at the top of La Liga. With Lionel Messi, Luis Suarez and Andres Iniesta on the bench, Barcelona went behind to the visitors in the 39th minute before Frenchman Jeremy Mathieu equalized in the 46th. Ibai Gomez then scored the winner in the 64th. Ronaldo, who had been out for two months with a knee injury, scored six minutes into his return as Zinedine Zidane's Real equaled the club's 1960-61 record of 15 successive league victories. The result left Real Madrid with nine points from three games, while Barcelona is fourth on six. Sevilla went second on seven points after beating third-placed Las Palmas 2-1. Atletico Madrid is fifth on five points after beating Celta Vigo 4-0 to earn its first win of the season. Having seen its two main title rivals win, the pressure was on Barcelona to see off opponent that drew with Atletico at the Vicente Calderon on the season's opening day. But with its top players rested by coach Luis Enrique after returning from international duty, long-haul flights and injury, Barcelona struggled to get going. New signing Paco Alcacer barely touched the ball in the first half and fired his only chance wide of the far post early in the second, while Ivan Rakitic spurned two good chances. Neymar was the only one of the MSN (Messi-Suarez-Neymar) trio to start, although he ended the game with the others by his side, but Barcelona still failed to create any more clear opportunities. "I'm the most responsible for what happens," Luis Enrique told reporters after the game. "It's easy to judge what happens with the benefit of hindsight. "From this clash we will take good things forward. We did not generate our usual chances and (Alaves) were very accurate. It's an ugly result for us but you have to congratulate the opposition." In the day's other game Villarreal won 2-0 away at Malaga with goals from Jaume Costa and Nicola Sansone. Monaco extend lead AS Monaco moved three points clear of Paris St Germain at the top of Ligue 1 Saturday after seeing off Lille 4-1 away, while Olympique Lyonnais fell to a second straight defeat when it was beaten 3-1 by Bordeaux at home. Monaco, which beat PSG 3-1 last Sunday in an early setback for Unai Emery's defending champion, was rampant against Lille, going 2-0 up inside 17 minutes after Djibril Sidibe's opener and Adama Traore's close-range finish. Fabinho added a third just after halftime with a thunderous finish and new signing Kamil Glik rounded off the rout in the 71st minute before Julian Palmieri volleyed in a late consolation goal for the host. The victory put Monaco top on 10 points, extending its lead over PSG, which was stunned Friday when St Etienne bagged a stoppage-time equalizer to secure a 1-1 draw. While Monaco's fine start to the season continued, Lyon slipped further off the pace after its defensive deficiencies were exposed by Bordeaux, despite taking a second-minute lead through Aldo Kalulu. Malcom responded for the visitors with a long-range effort in the 33rd minute. After OL captain Maxime Gonalons was red carded in the 67th, Bordeaux's Gregory Sertic and Jeremy Menez found the net as Hubert Fournier's side dropped to sixth on six points. — Agencies
