Feyenoord have made youngsters Kaj Ramsteijn and Anass Achahbar available for loan as they look for the pair to gain first-team experience.
Ramsteijn, 22, was signed from Excelsior at the start of last season and made seven Eredivisie appearances but has yet to feature this season, while 18-year-old striker Achahbar has made six brief substitute appearances and scored against Sparta Prague in the Europa League.
Technical director Martin van Geel told the club's official website: "Achahbar and Ramsteijn are two very talented players who are currently having to deal with tough competition in their positions.
"Therefore it is better for them in the second half of the season to get playing time with another club and develop further and come back to Feyenoord in the summer with more experience."
Defender Kelvin Leerdam, midfielder Kamohelo Mokotjo and forward Guyon Fernandez have all been told they can leave the club on a permanent basis, with Van Geel adding: "We currently have a large squad so these players are not likely to feature in the first team going forward.
"We have therefore let them know that they should look for another club to create a new boost to their career."
