Feyenoord are keen to sign Theo Lucius from PSV Eindhoven and have loaned out Mark Otten to NEC Nijmegen.
Lucius has been linked with a move away for some time, but interested parties were put off by PSV's asking price last summer.
It is believed that the Dutch champions have lowered their valuation by a sizeable amount and this has prompted Feyenoord to come to the table.
It is believed that Anderlecht are also keen to sign a player who has a deal which runs until 2007, but at this stage a move to Feyenoord seems a more viable option.
Defender Otten, meanwhile, is heading to NEC for next season in order to accrue experience.
Feyenoord coach Erwin Koeman feels the 20-year-old has a bright future in the game and he will look to prove himself at NEC.
NEC, meanwhile, have opted not to hand a contract to Kingsley Ikpotor.
The Nigerian attacker was invited to NEC for a trial and made a decent impression, but the club feel he would demand too much money as a non-EU player.
