Everton loanee Kurt Zouma has backed Richarlison to bounce back from his recent red card against Bournemouth.
However, the France defender admitted that his teammate might have been "too emotional" during Saturday's 2-2 draw at the Vitality Stadium.
After starting the season with three goals in his opening two games following a summer switch from Watford, the 21-year-old was sent off at Bournemouth for headbutting Adam Smith.
Richarlison will now sit out the next three games, including Wednesday night's EFL Cup second-round clash at home to Rotherham United.
"He is an important player for us," Zouma told reporters at Tuesday's pre-match press conference. "He is a very good player and is quite young.
"Maybe he was a bit too emotional [with the red card] but he is very young and a top quality player so he will bounce back and come back and help us."
Richarlison's impressive start to the season has seen him called up to the Brazil squad for the first time.
