HITC Sport understands from sources close to the club that Derby County have an option to make Omar Mascarell's loan move permanent, with several other clubs waiting in the wings to sign him.
Mascarell enjoyed a successful season on loan at Derby last term, making 30 appearances in all competitions before his season was cut short in March by a foot injury.
Mascarell's absence from the side coincided with Derby's dramatic late collapse, as they went from top of the Championship to eventually missing out on the play-offs.
Derby have the option in the loan deal to make Mascarell's move permanent and Rams boss Paul Clement is weighing up keeping the talented midfielder.
However, a number of other sides are monitoring the situation of the Real Madrid midfielder and are ready to rival the Rams for the 21-year-old's signature.
Former Derby boss Steve McClaren is thought be considering making a move to bring Mascarell to Newcastle United having been impressed by the Spaniard while working with him last season.
La Liga side Deportivo La Coruna have also expressed an interest in taking the central midfielder back to his homeland and are ready to pounce should Derby not take up their option on the Spain Under 21 international.
