Brazilian midfielder Casemiro will reportedly return to parent club Real Madrid following the completion of his loan spell with Porto.
The 22-year-old joined the Portuguese outfit on loan in July and has appeared in all but three games for his loan club this season.
According to Inside Spanish Football, Casemiro's development in Portugal has been closely monitored and Real Madrid are said to be impressed.
It was thought that Porto would attempt to sign Casemiro on a permanent deal next summer, but it appears that Los Blancos want the midfielder back at the Bernabeu for the 2015-16 campaign.
Real Madrid could attempt to recall the Brazilian international in January if Sami Khedira departs.
