In a thrilling match at the Emirates Stadium, Hector Bellerin rescued a late point for Arsene Wenger’s side after Marcos Alonso appeared to have secured victory for the Premier League champions.
For Fabregas, the former Arsenal captain was given a warmer reception than usual and was even applauded by some Gunners fans as he took some early corner kicks.
In the first half, the Chelsea midfielder was taken out by Sanchez and was promptly awarded a free kick.
And as Fabregas got to his feet, it looked as though he was going to have some harsh words for the Arsenal forward.
But instead, Sanchez and Fabregas hugged as Chelsea restarted play.
After the match, Sanchez took to Instagram to remind fans of the moment, as well as the fact that the pair remain good friends following their time together at Barcelona.
Fabregas also thanked Arsenal fans for their reception.
‘Great game at the Emirates. Should have won,’ he posted on social media.
‘Thank you once again for the reception.
‘We go again on Saturday. Thank you to the traveling fans, great as usual.’
