Thomas Tuchel believes it is "really hard to play against" Moise Kean after the Paris Saint-Germain forward continued his goalscoring form.
Kean, who is on loan at PSG from Everton, scored his fifth goal in as many games in Saturday's 3-0 Ligue 1 win over Rennes.
The 20-year-old's three goals in four Ligue 1 games are already more than the two he managed in 31 Premier League appearances for Everton.
Tuchel praised Kean's form for PSG, who are five points clear atop Ligue 1.
"[Kean] has a big heart, he puts on intensity. He is not afraid, he is courageous. He does what is necessary," the PSG coach told a news conference.
"I wouldn't want to be a defender against him right now, it's really hard to play against him.
"It's very important for us because we miss that in certain times."
Kean has scored two of his four big chances in Ligue 1 this season, while he has a shot conversion rate – excluding blocks – of 30 per cent.
After Kean's opener against Rennes, Angel Di Maria struck a brace for Tuchel's men.
PSG are next in action with a trip to Monaco on November 20.
