Remy became Chelsea’s fifth addition of the summer on Sunday, following the arrivals of Diego Costa, Cesc Fabregas, Filipe Luis and Didier Drogba.
And the 27-year-old, who has made the short journey across west London from QPR, admits he is hoping to discover his best form under the Portuguese coach.
"I spoke with him (Mourinho)," Remy told the club's official website after agreeing a four-year contract.
"He is very clever and he knows exactly what he wants. He has targets for me and I know I have a target for myself as well.
"Everybody wants the best so the discussion was really good. I know he can get the best out of a player and I'm looking forward to working with him."
The former Marseille striker knows he has work cut out to earn a place in Mourinho’s starting line-up following Costa’s impressive start to his Chelsea career.
The Spain international has scored four goals in his first three matches since completing a £32.5million switch from Atletico Madrid earlier this summer.
"We have two great strikers here already and I don't have a choice if I want to be in the team - I have to play at a very high level,” Remy said.
