MILAN — Defender Alessio Romagnoli was sent off as AC Milan's slumped to a 1-0 defeat at Genoa Sunday. Milan travelled to the Luigi Ferraris stadium looking for its third successive win following 3-2 victories over Palermo and Udinese but the Rossoneri were playing catch-up after just 10 minutes when Blerim Dzemaili beat Diego Lopez with a deflected free kick from outside the area. Their hopes were further dented when Romagnoli was sent off on the stroke of half-time for his second bookable offense, a foul on Diego Capel. Milan saw chances from Giacomo Bonaventura and Mario Balotelli, who started in place of Carlos Bacca, go off target while Capel tested Lopez with an angled drive that the Spaniard easily collected. Milan battled to get back into the game after the restart only to be frustrated at every turn. Milan is ninth, six points behind leader Inter Milan. On Saturday, Juventus' miserable start to the Serie A season continued as it lost 2-1 at Napoli, while Roma reignited its league campaign with a 5-1 drubbing of newly-promoted Carpi. Lorenzo Insigne and Gonzalo Higuain scored for Napoli before Mario Lemina pulled one back in a fast-paced, entertaining match at Stadio San Paolo. It was the four-time defending champion's third defeat in its first six league matches this season. Juventus lost just three all season last year, while it had only two defeats the previous campaign. Villarreal top In Spain, Villarreal went top with a 1-0 win over Atletico Madrid Saturday after a toothless Real Madrid was held 0-0 at home to 10-man Malaga and Lionel Messi suffered a serious injury as Barcelona beat Las Palmas 2-1. Villarreal's victory came courtesy of a goal from Leo Baptistao, who finished clinically having been found by Roberto Soldado inside the area after 14 minutes to secure its fifth straight win. Villarreal is surprise leader with 16 points from six games, a point more than Barca and two ahead of Real. Iago Aspas grabbed a 76th-minute equalizer to give fourth-placed Celta Vigo a 1-1 draw at Eibar. Ibrahimovic on target Zlatan Ibrahimovic underlined his return to scoring form as he helped Paris St Germain stretch its Ligue 1 lead to four points with a 4-1 comeback win at Nantes Saturday. The Sweden striker canceled out Yacine Bammou's early opener three minutes into the second half before Edinson Cavani, Angel Di Maria and Serge Aurier's goals put the champion on 20 points from eight games. Olympique Lyonnais now trails PSG by eight points after it slumped to a 3-1 defeat at Girondins de Bordeaux. Wahbi Khazri, Jaroslav Plasil and Pablo scored before the break in a one-sided encounter, with Lyon reducing the arrears through Claudio Beauvue 12 minutes from fulltime. — Agencies
