<p><br /> Arsenal captain Cesc Fabregas returned from injury to help the Gunners all but secure their place in the last 16 of the Champions League with a 5-1 romp against Group H rivals Shakhtar Donetsk.<br /> </p><p><br /> The Ukrainians had brought an impressive record to Emirates Stadium, defending a 100 per cent return so far in Europe, not to mention 15 wins from 17 games at home.<br /> </p><p><br /> However, Arsenal made them look ordinary, barely getting out of second gear as Alex Song was gifted an early goal following a terrible fumble by Shakhtar keeper Andrei Pyatov - and Arsene Wenger's men never looked back.<br /> </p><p><br /> In-form winger Samir Nasri smashed home his second goal in three days to make it 2-0 before the break, with Fabregas' spot-kick ending the game as a contest on the hour while Jack Wilshere and Marouane Chamakh completing the rout.<br /> </p><p><br /> Croatia striker Eduardo, sold during the summer, netted a fine consolation goal on the return to his former club with seven minutes left, which brought a round of applause from the home fans.<br /> </p><p><br /> Arsenal now head out to Donetsk in a fortnight knowing a point from their remaining three matches, one at home, would probably secure a top-two finish.<br /> </p>
