Tottenham boss Antonio Conte says Richarlison has transformed the team's approach.
His ability to get under opponents' skin was seen as an attractive quality to Conte, who wanted to make his team more streetwise this season.
Speaking ahead of Saturday's hosting of Wolves, Conte said: “For sure Richy is a player that made us focused, nasty. He's a player I like.
“He's always into the training session with his mind. For us I think this is a good sign.
“We are working also on the tactical aspect because the season will be long and there are many games that we have to play also with four strikers.
“In the end at Chelsea, we played with Lucas Moura as wing-back, (Ivan) Perisic - we are talking about in the past a striker -, Richarlison, Kulusevski, Sonny (and Kane).
“But to do this, it's important to have organisation in the tactical aspect."
