Arsenal and Chelsea played out an explosive contest on Wednesday night that saw both sides giving everything to take the three points, but it finished in a pulsating 2-2 draw.The Gunners took the lead at the Emirates Stadium early in the second half when a revitalised Jack Wilshere - taking his sixth start in a row for the club - spanked an effort past Thibaut Courtois in the Chelsea goal after an Alvaro Morata deflection.Their lead didn't last long though as the mercurial Eden Hazard made his way into the Arsenal box and Hector Bellerin naively lunged at the Belgian player and gave away a penalty.Although it was soft, Hazard picked himself up to convert from 12 yards and the game became instantly stretched. Then, on 83 minutes, Marcos Alonso stole in and scored from eight yards. Still, Hector Bellerin had a say in proceedings and met a half-volley to give Arsenal a point in injury time.Although it was 0-0 at half-time, the game had plenty of exciting moments in the first half too.And, it had its fair share of tasty tackles for a London derby.While Jack Wilshere and Cesc Fabregas exchanged yellow cards for fouls on each other, the latter was also involved in an incident with former Barcelona teammate Alexis Sanchez.With the Chilean trying to win the ball back from the Spaniard in Chelsea's box, the referee gave a foul even though it looked as if he may have got the ball.Fabregas lept to his feet to address Sanchez, but what followed came as a surprise to many fans. Watch the video below to see a refreshing exchange:

Fans on Twitter weren't upset with either man for hugging the enemy, instead, they quite enjoyed the touching moment.

Of course, Sanchez's future has been making headlines for months now and it's still questionable whether he will remain at the club past the January transfer window.

With his contract up in the summer, it's likely he'll move on regardless. However, boss Arsene Wenger insists quality replacements will be signed.

"How we cope with that [losing players], first of all we have not lost them [Ozil and Sanchez] yet, and secondly we will respond to that by bringing in players of top quality.

"This club has lost many, many big players and has always responded well. Massive players have left this club and the club will always be in a strong position on that front."
