Chelsea put aside slumping Premier League fortunes by beginning its UEFA Champions League campaign with a comfortable 4-0 win over Maccabi Tel Aviv.

Willian, Oscar, Diego Costa and Cesc Fabregas grabbed the goals as the host eased to three Group G points at Stamford Bridge.

Chelsea headed into the fixture on the back of collecting just four points from its opening five Premier League fixtures this season.

Eden Hazard has come under scrutiny during that below-par run of results, and his night started in similarly frustrating fashion when he blazed a penalty way over the crossbar in the sixth minute.

Jose Mourinho's men responded strongly, with the impressive Willian opening the scoring before being withdrawn with a hamstring injury.

But his replacement quickly picked up the baton, Costa winning a penalty that Oscar converted before netting himself.

The scoring was wrapped up in the 78th minute, Fabregas completing a good night's work by slotting into an empty net.

Chelsea's poor form did not have an immediate impact as it started impressively.

Fabregas freed Willian with a pin-point through-ball, only for the winger to be brought down by on-rushing goalkeeper Predrag Rajkovic.

Having been fortunate to avoid a red card, Rajkovic was thanking his luck again when Hazard missed the target. 

Undeterred, Chelsea continued to press forward and took the lead after 15 minutes.

Willian sent a perfect curling set-piece towards the back post and Rajkovic, stuck anticipating if somebody would touch it, could do little as the ball evaded everyone and flew into the top corner.

The Brazilian's impressive display lasted just 23 minutes, however, as he was sustained a muscle problem.

Chelsea was almost caught cold as the visitor spurned a chance to equalise.

Nikola Mitrovic delivered a pin-point set-piece and the prolific Eran Zahavi could only head over Asmir Begovic's crossbar.

That miss proved costly as the host was awarded another spot-kick just before half-time, Costa going down easily under a challenge from former Chelsea defender Tal Ben Haim. 

Oscar did not make the same mistake as Hazard when sending Rajkovic the wrong way.

The Premier League champion quickly picked up where it left off after the break, with Costa adding another in the 58th minute.

Oscar deserved much of the credit, his clever run meaning Fabregas's cross found Costa, who hammered an unstoppable shot into the net.

Chelsea opted for a more controlled approach thereafter, knocking the ball around confidently in a manner that belied the pre-match talk of decline.

A fourth goal still came, though, as Fabregas capped the performance when tapping home the rebound after Loic Remy had been denied by Rajkovic.
