The Irish are precariously placed bottom of Group C and need a victory against Vicente del Bosque's side to keep their tournament hopes alive.

Vicente del Bosque has come under criticism for his decision not to field a recognized striker in the opening match against Italy, which left Spain without a focal point to channel its attacks.
It is likely the Spaniard will opt to play with a forward in the central role against Ireland, with Fernando Torres in line to be given the nod ahead of Alvaro Negredo and Fernando Llorente, despite missing two good chances to defeat the Azzurri after coming off the bench on Sunday.
Cesc Fabregas will make way for Torres in the starting XI, as the 25-year-old may not be fully fit after carrying a thigh injury into the tournament.
Sergio Ramos and Gerard Pique will continue their partnership in defense in the absence of Barcelona captain Carles Puyol, who misses the championship after knee surgery.
Ireland has some slight injury worries going into the match against the current European champions. Richard Dunne is suffering from blisters and fatigue after the 3-1 defeat to Croatia, although the central defender will play through the pain barrier to partner Sean St Ledger in defense.
Shay Given and Darron Gibson also missed training early in the week but head coach Giovanni Trapattoni has stated that the pair are fit and ready to play. Shane Long is also in contention to start.
James McClean may also feel aggrieved not to have featured against Croatia in the opening match, but Trapattoni has spoken of not putting too much immediate pressure on the 23-year-old in the tournament, so if he does play it will likely be as a substitute.
