Speaking to the media, Slot said: "Sometimes the fixture list is more difficult than at other periods. PSG are one of the best teams in Europe at the moment. Newcastle were all over us in the Carabao final and Everton were so difficult with 10 people in their own 18-yard box all the time.
"I know Mo, he lives for goals. It would be weird if he was happy not scoring but probably his biggest quality is he can play a poor game and still score so his head is not all over the place. That is why he scores so many, because he wants it so much. Yes, there were probably periods this season he smiled a bit more but that's not just him, it's all the players."
