Chelsea and Arsenal served up a five-goal thriller as the Blues ended on the right side of a classic Premier League clash played at Stamford Bridge on Saturday evening.
The 2012 Champions League winners took the lead as early as the ninth minute through Spanish forward Pedro Rodriguez.
Arsenal striker Pierre-Emerick Aubameyang wasted a glorious opportunity to level proceedings for the Gunners and he was swiftly punished when underfire Spanish star Alvaro Morata doubled the lead for Chelsea on 20 minutes.
The visitors continue to pass up decent opportunities with Armenian international playmaker Henrikh Mkhitaryan also missing a similar chance to that of Gabonese star Aubameyang.
Mkhitaryan redeemed himself with a near-post finish to reduce the deficit for the North London giants before he teed up the equaliser for Super Eagles forward Alex Iwobi all in the space of four minutes.
The introduction of World Cup stars Mateo Kovacic and Eden Hazard in the second half tilted the game towards the hosts.
The aforementioned Hazard was particularly influential as he provided the assist for Marcos Alonso to score the winner for the Stamford Bridge outfit nine minutes from time thus giving Chelsea a 3-2 win over their rivals in the London Derby clash.
The win takes Chelsea to the top of the Premier League table ahead of Tottenham, while the Gunners join other clubs like Fulham and West Ham United on zero point after two league matches.
