Gary Cahill has called out Sergio Aguero for his "crazy tackle" on David Luiz In the aftermath of Chelsea's stunning 3-1 win over Manchester City at the Etihad Stadium on Saturday.
The England defender scored an own goal in the first half but Antonio Conte's charges came storming back with goals from Diego Costa, Willian and Eden Hazard to cap off a solid victory for the league leaders.
While the goals were of good quality, the game was marred by an ugly fracas in the dying seconds when Aguero went flying in and caught Luiz, sparking a free-for-all that saw the Argentine and Fernandinho sent off.
Luiz received treatment for a lengthy period but managed to get back up on his feet as referee Anthony Taylor blew the final whistle.
"Maybe it was a bit of frustration," Cahill told The Mirror. "It was unlike him [Aguero], it was out of character for him. It looked a bad tackle, out of character, it is disappointing to see that.
"They'd had a battle, him and David, and sometimes a bit of frustration spills over.
"It was a crazy tackle, not like him."
Chelsea will hope to extend their lead at the top when they play hosts to West Bromwich Albion next Sunday.
