Chelsea began their Premier League campaign with a commanding two-goal victory over Hull City in Jose Mourinho's first game back in charge of the West London club. The Blues dominated from the word go and had a penalty after five minutes to take the lead, but Frank Lampard saw his effort saved by Allan McGregor, who had needlessly taken out Fernando Torres to concede the spot kick. The deadlock was broken soon after in the 13th minute when debutant Kevin de Bruyne slid in Oscar to poke under the onrushing McGregor. After again being denied by McGregor's right hand, Lampard got his goal midway through the opening half when his 30-yard free kick dipped and swerved to deceive McGregor. Goal-line technology was used for the time in English football right on half time when Branislav Ivanovic's point-blank header was somehow pushed away under the crossbar by Scottish international McGregor. Jon Moss's watch must not have flashed 'GOAL' and virtual images showed that all of the ball did not cross the line. The second half was much more languid as Chelsea eased off the gas and saw the result home. In fact, Hull came closest to scoring the third goal when Curtis Davies rose highest to meet Ahmed Elmohamady's cross and head goalwards but it was well held by Petr Cech. Down the other end Lampard rocketed another free kick inches wide as Mourinho gave debuts to Andre Schurrle and Marco van Ginkel. Schurrle almost opened his account instantly but chipped narrowly over the crossbar with just McGregor to beat.
