Albert Celades’ Spain U21 side could pick up their fifth win in five games in European Championship qualification, if they beat Northern Ireland on Thursday evening.
The national side will travel to Shamrock Park on Thursday in search of their fifth straight win the competition, although they come up against their closest rivals in Group B.
Celades’ side have played one less game than the rest of the group but still sit top of the standings after four wins in four games.
A victory on British soil will see them all-but seal qualification for Euro 2019 next year.
The former Barcelona midfielder has handed debut call-ups to five players, which include Middlesbrough’s Adama Traore, who has been impressing this season in the English Championship.
Jorge Mere, Jesus Vallejo, Dani Ceballos and Mikel Oyarzabal add experience, whilst Borja Mayoral of Real Madrid will lead the attack.
For Northern Ireland, a win over Spain would put the top of the group, but manager Ian Baraclough has to pick from a host of part time footballers.
A second-placed finish could still be enough to secure a qualification play-off, but hopes are still alive for qualification to the competition next year in Italy and San Marino.
