Luton Town aren't giving up on landing LDU Quito midfielder Oscar Zambrano.
The Ecuadorian youngster has been the subject of transfer talks between the two clubs for months.
Zambrano is keen to make the move, but the two clubs are still struggling reaching terms.
The Sun says Luton have brought in an agency to assist in negotiations.
The Hatters are leaning on the agency in negotiations for a deal which will cost 15-20m.
