Coach Mike Ford hopes rugby union does not follow football into dramatic wage increases, despite Bath splashing out on Taulupe Faletau.
Faletau signed a three-year deal with the Aviva Premiership club on Wednesday after rejecting the offer of a dual contract with the Newport Gwent Dragons and Wales.
The 25-year-old back-row is believed to be one of Bath's two marquee signings, along with international team-mate Rhys Priestland, which means his wage does not count against the club's salary cap.
English clubs will have increased spending power over the next two seasons as well, but Bath head coach Ford has warned the battle to try and match salaries in the French Top 14 could lead to football-style wage increases in the near future.
"Trevor Francis was the first £1m footballer. Now players are getting close to £1m per week," Ford said.
"We've got to be careful not to create a monster because otherwise it will become like football. It's everyone's responsibility within the sport for it not to be like that. Hopefully we've still got a lid on it.
"People have worked really hard to bring more money into the game through TV rights and a new agreement is being negotiated with England which will bring in extra money as well.
"The key is that when the money comes in, it doesn't all go into the players' pockets. We need to think about the infrastructure of the sport and the stadium and people working there.
"It's difficult because players and agents see all that money coming in and think 'we want a piece of that'."
