( CNN ) -- A clinical second half strike from Samuel Eto ' o sealed a famous Champions League victory for Inter Milan over Chelsea to cap a triumphant return to Stamford Bridge for their coach Jose Mourinho . The Cameroon striker seized on a fine through pass from Wesley Sneijder to score the only goal of the second leg in the 78th minute to give the Italian champions a 3-1 aggregate victory . It was no more than Mourinho and his men deserved after having several excellent chances to put the tie beyond Chelsea 's reach . Inter led the last 16 clash 2-1 from the first leg in the San Siro , but many were expecting English Premier League title challengers Chelsea to overturn the deficit . But they reckoned without the tactical wiles of their former manager Mourinho and Carlo Ancelotti 's men scarcely created a chance throughout the 90 minutes as the prolific Didier Drogba and strike partner Nicolas Anelka were blunted . To cap a dismal evening for Ivorian international Drogba , he was sent off five minutes from the end for a stamping incident on Thiago Motta in the Inter penalty area . Former Barcelona star Eto ' o had begun his evening by wasting an opportunity to put his side further ahead in the opening skirmishes as a John Terry mistake left him to head tamely at Ross Turnbull from close range . A feature of the first half was a number of last-ditch blocks by Inter defenders , the first by Maicon as Drogba was left with a clear sight of goal . Walter Samuel also denied Florent Malouda and Chelsea appealed in vain for a penalty when Motta tangled with Branislav Ivanovic after a corner . Chelsea ended the half besieging the Inter goal and their prospects looked bright for the second half , but it was Inter who proved the more dangerous on the break . Sneijder exploited gaps on the Chelsea defense and from his pass the best chance fell to Argentine Diego Milito but he scuffed his shot wide of Turnbull and the goal . Motta also headed wide from close range , but when Eto ' o was given the same opportunity he showed his quality and might have added another but for a fine save by Turnbull after Drogba had left Chelsea with 10 men . Mourinho said his team had given the `` perfect performance '' but was growing concerned after they had wasted several excellent chances . `` When we did score , Chelsea were completely out of the game . I thought everything was superior , not just our tactics but our attitude on the pitch , '' the Portuguese coach told Sky Sports .
