Anderlecht are preparing for an auction for their teen sensation Romelu Lukaku.
The striker is wanted by Europe's biggest clubs.
Anderlecht president Herman van Holsbeeck said: "Our price will be around 30million [£25.2m].
"We received one offer from an English club three days before the end of the August transfer period. It was 10m [£8.4m] immediately and 10m in one year. We would not accept the offer because we wanted to keep the player."
That club is believed to be Chelsea and Van Holsbeeck continued: "I think he will go to the Premier League. For him the team is in England. We know that Chelsea, Tottenham and Liverpool are interested in him and that they follow the player.
"There is some interest from Real Madrid but we know they are interested in every good young player. What for us is the right club? The Premier League clubs from the UK are the biggest clubs in the world with a lot of money. In Spain you have only Real Madrid and Barcelona who have big money. In Italy there is also the financial crisis.
"At the end of the season it will be difficult for us to keep him. I know he was a supporter of Chelsea when he was a young boy. If Manchester United, Manchester City or Tottenham come in for him, it is also an interesting prospect."
