PSV Eindhoven are hoping to extend deals with defensive duo Slobodan Rajkovic and Alcides into next season.
Both players are on loan from Chelsea with 23-year-old Alcides moving to Eindhoven at the start of 2007 and Rajkovic, 19, following his team-mate six months later.
They have clocked up 34 league appearances between them this season to help PSV retain their Eredivisie title, and technical manager Stan Valckx is hoping they will remain at the Philips Stadion into the new campaign as well.
'We really want to keep both players here,' he told Voetbal International. 'I cannot say if that is possible, it is difficult to predict.
'For Alcides especially. They have already loaned him out for four years and I don't know if that is their intention for next season too.'
