MILAN (AFP) - Jose Mourinho got one over his former employers as Inter Milan beat Chelsea 2-1 in the Champions League last 16, first leg clash at the San Siro here on Wednesday. Its a slender advantage but a crucial one for Inter ahead of the second leg at Stamford Bridge on March 16th and also represented a milestone as it was the first victory for the Italians against an English team since 2003 and a 3-0 win over Arsenal in London. For Chelsea coach Carlo Ancelotti it was an unhappy return to the stadium where he served AC Milan for eight years with such distinction, winning two Champions League titles and one scudetto. Mourinho did not gloat over taking a slender advantage to London in three weeks time. Of course I am happy inside, said the Portuguese. Because as a professional I want to win and as a professional I want to win more trophies than anyone else. There were no surprises from us tonight (Wednesday) and Chelsea didnt have any either. We are evenly matched sides. Chelsea are not better than us, they have different qualities just as we do. Inter were off to a flying start and went ahead after just three minutes following some shoddy defending by Chelsea, as Thiago Motta played the ball into Samuel Etoo who fed it on to Diego Milito, the Argentine cutting too easily inside the wrong-footed John Terry and shooting home at Peter Cechs near post. Chelsea midfielder Frank Lampard, who was returning after missing last weekends match because of a virus, said that the early goal conceded to the Italians had knocked the stuffing out of them. I felt overall we were the stronger team but them getting the early goal made it more difficult for us, said Lampard. But going back to Stamford Bridge at 2-1 makes it fairly even but obviously we have got to win the match itself. It was just the dream start Inter would have wanted but Chelseas reaction was awe-inspiring as the visitors took total control. Their first chance came on 11 minutes as Nicolas Anelka shot wide of the near post before a minute later Salomon Kalou twisted and turned on the edge of the box but shot straight at Julio Cesar. Then up stepped Didier Drogba on the quarter-hour mark to crash a free-kick from 25 yards against the cross-bar and follow that up with a fine effort that forced Cesar into a sprawling save. Cesar then had to parry from Michael Ballack and Drogba hooked a volley wide after controlling the ball on his chest in the box and then sent another volley wide when fed by John Obi Mikel. The half ended in controversial fashion as Samuel appeared to trip Kalou in the box referee Manuel Gonzalez waved away Chelsea appeals. Chelsea got what their play deserved just six minutes after the restart but from some poor Inter defending. Motta let Branislav Ivanovic run forward from right back to the edge of the Inter area without a challenge before the Serbian cut across the box and tapped the ball out to Kalou, whose nonchalant side foot from 20 yards somehow found its way through a crowd of defenders and past Cesar, who possibly should have done better. And yet four minutes later Inter were back in front as Esteban Cambiassos wild shot from distance, which was going wide, struck Ivanovic in the midriff and came back to the Argentine whose second effort deceived Cech and found the far corner. Mourinho then made the surprising move of bringing on striker Mario Balotelli for Motta while Cech suffered what was first thought to be a knee injury but was later diagnosed as a calf problem and was replaced by Henrique Hilario. On 65 minutes great play between Drogba and Anelka teed up Lampard but Cesar parried his close range effort. Chelsea dominated the ball but created little in the way of clear cut chances in the final stages and it is advantage Inter and Mourinho. Gonzalez wonder goal earns CSKA draw against Sevilla CSKA Moscow came from behind to draw 1-1 with Spanish side Sevilla in their Champions League last-16 clash here on Wednesday, leaving the return leg in two weeks time delicately poised. CSKA bore little resemblance to a team that had not played a competitive match since December, producing some electric counter-attacking play down the flanks. Chilean winger Mark Gonzalez produced a spectacular equaliser on 65 minutes with a 35-yard strike that is likely to be a contender for goal of the season, swerving past a helpless Andres Palop. The home side could have added a second on 84 minutes when Czech striker Tomas Necid picked up the ball inside the Sevilla penalty area, only for his left foot shot to be saved by the 36-year-old custodian. Sevilla coach Manuel Jimenez said he wanted to win at Moscow but added he was also pleased with a draw. We managed to grab a positive result here though it wasnt easy at all, he said. We had to adapt ourselves to the synthetic pitch to keep the ball under control. We scored before the break but Gonzalez equalised in the second. He scored a goal that is typical of him. A draw in the away match is a positive result. But anyway now we will need to seal the result in the return match. Deprived of top scorer Luis Fabiano and a recovering Frederic Kanoute, the Spanish side lacked composure in front of goal and only took the lead with their first clear-cut chance of the game thanks to a defensive blunder. A Jesus Navas cross evaded the entire CSKA defence, leaving Alvaro Negredo, who came into the match on the back of two red cards in the last three Spanish championship matches, to creep in behind for a simple tap-in on 24 minutes for his first Champions League goal of the season. CSKA coach Leonid Slutsky admitted the Spaniards had the advantage but vowed they would be no push over in the second leg. We wanted to win very much but failed to keep a clean sheet, he said. After that Sevilla played very good defensively but we managed to level and had chances to score the winner. Now the Spanish side have more chance to go through but we are going to fight up to the very end. Everything will be decided in the return match. Much of the pre-match hype had centred on CSKAs Serbian midfielder and reported Bayern Munich target Milos Krasic but tight marking by Sevillas midfield enforcer Didier Zokora limited the 25-year-olds influence on the game. That left Japanese midfielder Keisuke Honda to provide the driving force for the Russian teams attacking play and he came close to adding his own name to the scoresheet on 31 minutes, firing just wide from 18 yards. The 9-million-euro signing from Dutch side VVV-Venlo, making his first appearance for Slutskys men, narrowly missed the target again minutes later when he picked up a rebound from an Evengi Aldonin effort. The Russian Cup holders could have opened the scoring after only four minutes when Sevillas French centre-back Julien Escude carelessly gave away possession to CSKAs Czech striker Tomas Necid. The 19-year-old centred to former Liverpool man Gonzalez, who volleyed high and wide over Sevillas crossbar. Necid had his own chance three minute later when he ran onto a Keisuke Honda pass, only for Sevilla keeper Palop to comfortably palm his shot wide. The return leg takes place on March 16 in Seville.
