Bournemouth forward Rayan is seeking revenge on Erling Haaland when his side face Manchester City in their Premier League opener, following Brazil's World Cup defeat to Norway.
The 20-year-old was part of the Brazil side beaten by Haaland's Norway in the round-of-16 in north America this summer, and the two may meet on pitch on Sunday as both sides get their Premier League campaigns under way.
Asked by ESPN Brazil if he intends to get back at the City striker when the pair meet, he said: "Definitely. I'm going to have to get my revenge on him."
"It's one of the toughest games you can possibly have, especially away from home. They lost the title, so they'll come into it with a lot of motivation."
City battled with Arsenal in the previous campaign and looked to have taken the advantage at one stage after beating the Gunners in April -- but dropped points in the run-in saw their challenge slip away.
Rayan suggested the outcome of the previous title race might impact City, who will also be without the services of Ballon d'Or winner Rodri after his completed transfer to Barcelona.
"When you lose a title, your confidence can change a little. They also lost Rodri to Barcelona, a very important player in the build-up and creation of their attacks."
Rayan joined Bournemouth midway through last season and scored five goals in 15 Premier League appearances as the club secured Europa League qualification.
He also featured for Brazil at the World Cup while still a teenager, starting the round-of-16 defeat among four appearances at the tournament.

"After a World Cup, people look at you differently. The World Cup gives a player a certain status and carries a lot of weight. Now I have to make the most of that."
"I was 19 when I played at the World Cup, and I turned 20 on August 3. Once I became a starter and started playing regularly, I matured a lot."
Bournemouth are newly under the stewardship of Marco Rose -- who replaced Andoni Iraola after his move up to Merseyside -- and are in the Europa League for the first time.
"We had a great preseason. He's a very tactical, attack-minded manager and likes his teams to press high. The squad has really taken to him," Rayan said of the German, who last managed RB Leipzig in the Bundesliga.
"It's the first time the club has played in this competition, and we're going to give everything to go as far as possible. Who knows, maybe we can win it.
"Our goal is to have an even better season than last year. That's what we're working towards. We want to challenge for European places again."
