Chelsea centre-back Gary Cahill says Paris Saint-Germain striker Zlatan Ibrahimovic is very vocal on the pitch and loves hearing his own voice.
Both players will square off against each other in the second leg of the Champions League's last-16 tie at Stamford Bridge on Wednesday.
The Swedish international was sent off last season in the game between the two sides at Stamford Bridge but Cahill is backing him to bounce back such is his desire on the big stage.
"He's a top player, one who can be very dangerous on his day," said Cahill.
"For him, it was unfortunate the last time around but for his team it was positive because they went through.
"This tie is settled perfectly but he is very vocal on the pitch - he does like the sound of his own voice - but he deserves respect and he's one we have to look out for."
