Chelsea fans noticed Hakim Ziyech and Romelu Lukaku exchanging some frustrated words during Tuesday's Premier League clash against Brighton.
The Blues broke the deadlock in the 28th minute at the Amex Stadium through Ziyech, who fired a powerful low strike past Robert Sanchez.
However, the Moroccan playmaker refused to celebrate, casually walking away after he had seen the ball go into the back of the net.
