Spain youth international Jese is training with Real Madrid's first team squad.
With coach Jose Mourinho unhappy with his attacking options, No2 Aitor Karanka recommended he call up Jese from the youth team.
Mourinho immediately agreed and had the young striker train with the seniors on Thursday and Friday.
Jese is yet to even taste Castilla action, but has scored nine goals in 14 games for the 'A' youth team.
"He's a crack," declared one senior player as the squad came off the training pitch on Thursday.
