( CNN ) -- Brazilian striker Neymar marked his El Clasico debut with a goal as Barcelona beat Real Madrid 2-1 at the Nou Camp on Saturday to consolidate their lead at the top of La Liga . Neymar , who joined the Catalan club for â‚¬57 million ( $ 78 million ) in the summer , opened the scoring in the 18th minute , side-footing a low right-foot shot past Diego Lopez after being played in by Iniesta . Despite fielding world-record signing Gareth Bale alongside Cristiano Ronaldo , Real could n't find a route though a well-organized Barcelona defense . Ronaldo went close in the 58th minute -- his low right-foot shot forcing a smart save from Victor Valdes -- and Karim Benzema ( who replaced Gareth Bale in the 61st minute ) hit the woodwork in the 72nd minute with a sweetly struck shot from 20 yards . But it was Gerardo Martino 's team who delivered the killer blow seven minutes from time as substitute Alexis Sanchez scored with a delightful chip over Lopez . Jese Rodriguez pulled one back for Madrid in the 90th minute but it could n't stop Barcelona winning a first league match over their arch rivals since December 2011 . The win sends Barca four points clear at the the top of the league with nine wins and a draw from their opening ten games . Defeat keeps Real Madrid in third place with 22 points . Second-placed Atletico Madrid can move five points clear of their city rivals with a win over Real Betis on Sunday evening . Elsewhere , Malaga 's miserable run of form continued with a crushing 5-0 home defeat to Celta Vigo . The visitors were a goal up after six minutes thanks to a long-range shot from Alex Lopez before Argentine international Augusto Fernandez doubled the lead in the 23rd minute . Lopez bagged his second in the 64th minute with Nolito adding Celta 's fourth in the 73rd minute . Brazilian striker Charles completed the rout with a fifth nine minutes from time . In the remaining two La Liga fixtures , Levante moved up to seventh after beating Espanyol 3-0 and Granada rise to 11th place after beating Elche 1-0 .
