Soccer-European roundup-Man City crush United as Barca roll on

Sept 22 (Reuters) - Manchester City embarrassed cross-town rivals Manchester United 4-1 in their first derby of the Premier League season while Barcelona maintained their perfect start to La Liga with a 4-0 victory at Rayo Vallecano. Borussia Dortmund stayed on top of the German Bundesliga, despite dropping points for the first time, and Inter Milan crushed a hapless Sassuolo 7-0 in Serie A with Diego Milito scoring twice in his first match back from injury. - - ENGLAND Manchester City thrashed champions Manchester United 4-1 at the Etihad stadium as City manager Manuel Pellegrini saw his team climb to third in the Premier League with 10 points, two behind leaders Arsenal and Tottenham Hotspur, who recorded wins over Stoke City and Cardiff City respectively. German international Mesut Ozil played a part in all three of the Gunners' goals in their 3-1 win and Tottenham snatched all three points thanks to a late winner from Brazilian Paulinho. While things are all flying high in north London, Manchester United find themselves in a lowly seventh place with just seven points from their opening five games. Chelsea took some of the heat off Jose Mourinho with a 2-0 win at home to Fulham but Liverpool's bright start to the new season hit another snag as they were beaten 1-0 by Southampton at Anfield. - - SPAIN Barcelona stayed on top of La Liga by maintaining their perfect start with a 4-0 victory at Rayo Vallecano but Atletico Madrid are right on their heels after a 2-0 win over Real Valladolid made it five wins from five to leave them second on goal difference. Real Madrid were without the world's most expensive Gareth Bale for the visit of Getafe after the Welshman injured himself in the warmup. But it mattered little as Cristiano Ronaldo scored twice in a 3-1 win which lifted Carlo Ancelotti's team to third with 13 points from five matches. Promoted Villarreal remained unbeaten on their return to the top flight but slipped down to fourth with 11 points, after being held to a 0-0 draw at Celta Vigo. - - GERMANY Sparkling Bayern Munich crushed Schalke 04 4-0 with Bastian Schweinsteiger on target in his first start since returning from an ankle injury. Bayern top scorer Mario Mandzukic, Franck Ribery and substitute striker Claudio Pizarro also found the back of the net as the treble-winning Bavarians notched their fifth win in six league games to join Borussia Dortmund on top of the Bundesliga. They also extended their unbeaten run to 31 games, five short of the all-time Bundesliga record. Dortmund, who remain league leaders because of a superior goal difference, dropped their first points this season, drawing 1-1 at Nuremberg, after winning their first five games of the campaign. Bayer Leverkusen continued their stellar run with a 4-1 demolition of hosts Mainz 05 to stay within one point of the leaders, in third place on 15. - - ITALY Diego Milito scored twice after coming on as a second-half substitute in his first appearance after a seven-month injury layoff to help Inter Milan rout hapless Sassuolo 7-0 away in Serie A. Inter now have 10 points from four games and are unbeaten but they trail leaders Napoli and AS Roma who both recorded their fourth straight wins. Napoli capitalised on a rare penalty miss by Italian international Mario Balotelli as they won 2-1 at AC Milan, while AS Roma ended a five match winless run against arch-rivals Lazio with a 2-0 win which maintained their 100 percent record. Spaniard Fernando Llorente scored his first goal for Juventus to give the titleholders a 2-1 win over Verona. - - NETHERLANDS PSV Eindhoven took over as leaders of the Dutch league after they scored four goals in 15-minutes on the way to a 4-0 win over champions Ajax Amsterdam. PSV moved two points clear at the head of the standings on 15 and remain the only unbeaten side after seven rounds. Ajax stay on 11 points, amid a cluster of clubs. PEC Zwolle were deposed from top place after losing for a second successive week, this time 3-0 at Vitesse Arnhem for whom Brazilian teenager Lucas Piazon, on loan from Chelsea, scored twice. - - FRANCE Monaco and Paris St Germain battled to a 1-1 draw in the French Ligue 1 clash of the summer's big spenders in Paris. Radamel Falcao cancelled out the goal scored by PSG's Zlatan Ibrahimovic as Monaco remained on top of the table with 14 points from six games, two ahead of PSG in second and St Etienne in third. The highly anticipated confrontation between the Qatari-backed champions and the ambitious Monaco, who have splashed out around 170 million euros ($229 million)in transfers this summer, did not prove as spectacular as had been hoped. Some big names failed to shine, especially Edinson Cavani, the Ligue 1 most expensive player ever after PSG paid 64 million euros ($86.46 million)to Napoli to land him in the off-season. - - GREECE Olympiakos Piraues dropped points for the first time this season but they stayed on top of the Greek Super League after a goalless draw at Panaitolikos. Olympiakos lead the standings with 13 points, with PAOK Salonica second, one point adrift following a 1-0 home win over Platias. Panathinaikos returned to winning ways with a 1-0 home win over OFI Crete thanks to a goal from Swedish striker Marcus Berg, a result which moved the Greens up to fifth place with eight points. - - AUSTRIA FC Salzburg striker Jonathan Soriano continued his prolific season by scoring again as the Austrian Bundesliga leaders drew 2-2 at home to Wolfsberger AC. Soriano's 55th minute goal, which put Salzburg 2-0 up after a first-half effort from Senegal striker Sadio Mane, was the Spaniard's 12th in nine league games this season and his 15th in all competitions. However, the visitors hit back when Michael Liendl and Sandro Gotal scored in the last half hour. Salzburg stayed top with 19 points from nine games, two clear of promoted Groedig who drew 2-2 with Wacker Innsbruck. - - SWITZERLAND FC Basel followed up their Champions League win at Chelsea by recovering from an early shock to beat FC Sion 3-1 away. Brazilian Leo Itaperuna gave Sion a 23rd minute lead before Basel hit back through Valentin Stocker, Giovanni Sio and Marco Streller. Basel pulled level at the top with Young Boys, who lost 1-0 at home to FC Lucerne, and Grasshoppers, who beat FC Thun 2-1. ($1 = 0.7402 euros) (Compiled by Tom Bartlett; Editing by John Mehaffey)
