The report in the German publication has claimed that Leeds have made an offer for the 26-year-old winger, and so have Fulham, Fiorentina and Sevilla.
However, according to the report, the offers are not enough, and what Mainz are asking for, none of the clubs are prepared to pay.
Boetius’s agent Erkan Alkan is quoted as saying by Bild: “We have four offers.”
Stats
Boetius made 26 starts and two substitute appearances in the Bundesliga for Mainz this past season, scoring four goals and providing five assists in the process, according to WhoScored.
During the 2018-19 campaign, the 26-year-old Netherlands international winger made 25 starts and five substitute appearances in the league, scoring four goals and providing seven assists in the process, according to WhoScored.

Advice for Ben White
Meanwhile, Newport County manager Michael Flynn has said that he would like Ben White to join Liverpool in the summer transfer window.
White spent the 2019-20 campaign on loan at Leeds from Brighton and Hove Albion.
According to talkSPORT, Leeds want to sign the 22-year-old defender on a permanent contract, and have had a bid of £22 million for him turned down by the Seagulls.
The Daily Star has reported that Premier League champions Liverpool are planning to make a £20 million bid for the youngster.
Flynn managed White during the defender’s loan spell at Newport, and he hopes that the youngster moves to Liverpool this summer.
Flynn told talkSPORT: “I’d love to see him at Liverpool. I know Pep Lijnders, the assistant, he’s an unbelievable coach.
“So I know he will help Ben improve. He’s got to do what’s best for Ben White. That could be getting a season in the Premier League with regular games at Brighton, which I think he could do.
“[Brighton boss] Graham Potter might want to keep him and bring him on and then sell him for more money after a year in the Premier League. That’s a decision for Ben, but for biased reasons, I’d be edging him towards Liverpool.”
