Eintracht Frankfurt have been informed that Manchester City now want to sign Omar Marmoush immediately.
The German club are demanding around £67m (€80m) for the 25-year-old.
There is no release clause for the forward and offers significantly below that are expected to be rejected by the Bundesliga club, who are third in the German top flight.
City and Marmoush's camp consider a transfer fee of £42m- £50m (€50-€60m) to be more realistic.
There have been no negotiations between the clubs yet.
Marmoush, who can operate across the front three, has scored 13 goals in the Bundesliga so far this season with only Bayern Munich striker Harry Kane scoring more.
He has netted 18 goals in all competitions this campaign and is second only behind Liverpool forward Mohamed Salah for goal involvements across the top five European leagues this season.
Meanwhile, Manchester City have approached Palmeiras over a deal for Vitor Reis.
Discussions are in the early stages but City want to sign the talented 18-year-old centre-back.
Palmeiras are understood to be hopeful of a fee in the region of £33.5m to £40m.
The defender made 22 appearances last season for Palmeiras, scoring two goals.
He also captained Brazil's U17 team at the U17 World Cup in 2023.
South American football expert Tim Vickery speaking to Sky Sports News' Transfer Talk about Vitor Reis:
"Palmeiras are in the Club World Cup and they very much want to keep hold of this centre-back, who turns 19 next week.
"I don't think he's anywhere near Premier League ready at the moment. He's classy but he needs to fill out physically.
"Palmeiras have been producing a lot of good players recently - most of them attackers.
"If you were to put him in the Premier League at the moment, he would really be bullied. So, perhaps it serves everyone's interests for him to stay a little bit longer in Brazilian football.
"But Palmeiras, are reluctant to sell before that Club World Cup."
