Former Chelsea defender William Gallas was at Stamford Bridge as his two former teams clashed on Saturday.
Gallas was shocked at how Antonio Conte stood all through the game passing instructions to his players.
“I was just behind him [at Stamford Bridge] and for 90 minutes the manager was talking to his players – I was shocked,” he told talkSPORT.
“Some managers stand up to give some information to their players and go back to their bench. But all the time he stands up!
“After the game I had the opportunity to speak to Antonio Conte and I asked if the manager was always like this and he said ‘Yes!'”
