West Ham starlet Domingos Quina will be the centre of attention when Portugal Under-19's host Spain.
The 17-year-old will play for his country in Lisbon on Tuesday ahead of returning to new club manager David Moyes.
A host of Premier League scouts will attend the game with the remit of watching midfielder Quina ahead of a potential January move.
The Hammers could let Quina leave on loan when the transfer window reopens, but Moyes will have a look at the teenager before a final decision is made.
