[ad_pod ]Arsenal fans have reacted in disbelief after Mike Dean, so often accused of having a soft spot for Tottenham, awarded their side a penalty in the north London derby.The Gunners were gifted the opportunity to open the scoring at the Emirates after Jan Vertonghen foolishly swatted a cross into the box away with his hand, prompting Dean to point to the penalty spot.Pierre-Emerick Aubameyang coolly converted from 12 yards to rise to the top of the Premier League scoring ranks, making him a good option to use your bet365 sign up bonus for the golden boot on, but Gunners' fans were more in awe of the referee's decision rather than the Gabonese international's proficiency in front of goal.Dean has often been seen running off waving his arm in the air when Spurs score in games that he has officiated in the past.
