Anderlecht have said they are in talks with Chelsea over the possible transfer of Romelu Lukaku to Stamford Bridge.
The 18-year-old Belgian striker has been linked with a move to the Premier League runners-up for a few months.
Anderlecht general manager Herman van Holsbeeck said: "There is still a long way to go in the negotiations.
"We are indeed negotiating with Chelsea, but there are other clubs we are talking to."
The teenager has also been linked with Chelsea's Premier League rivals Arsenal, Manchester City and Tottenham.
He was linked with a move to England in January
but instead stayed with Anderlecht until the end of the season.
The transfer could involve potential signing Kevin De Bruyne joining the Brussels club on loan.
Van Holsbeeck added: "It could happen in the next half hour, it could take until 31 August - that is football."
Chelsea appear to be negotiating transfers despite being without a manager since May following the departure of Carlo Ancelotti.
This week they were reported to have
had a £22m bid for midfielder Luka Modric rejected by Tottenham
