Considering all the hype, all the arguments and all the debates, as Spain battled with Brazil over Diego Costa ahead of the 2014 World Cup, the former Atletico Madrid striker has yet to deliver for his country of choice.
The Brazilian-born player was unable to help Spain's cause at the World Cup, and since then, has managed just three appearances for La Roja, which saw a return of one goal amidst two defeats and one victory.
Hardly inspiring numbers, from the man who it was hoped, would spearhead Spain to continued international glory, with that solitary goal coming in the EURO 2016 qualifier against lowly Luxembourg, during an unsurprising 4-0 victory.
Since moving to Chelsea last summer, Costa has been at the centre of more arguments and debates, particularly between Jose Mourinho and Vicente del Bosque, with the two managers coming to blows over the striker's selection.
Previous squad calls for the 26-year-old annoyed Mourinho, who claimed Costa wasn't fit, needed to be rested and that his club had provided detailed medical details, to their Spanish counterparts.
In Spain, speculation began to mount that Costa wasn't really interested in playing them. Something which the player vehemently denied.
To prove a point, even though Spain had accepted Chelsea's explanations that he was injured for the last squad call in March, Costa still travelled to Madrid, in order to undergo a medical evaluation, before returning swiftly back to London. This was aimed at showing his desire and willingness.
On Tuesday, Vicente del Bosque announced his squad for the June matches against Costa Rica and Belarus, with Costa a notable absence from his list of players.
Injury problems remain an issue, and at a press call following the announcement of his squad, Del Bosque explained why Costa hasn't been included this time around.
"He has muscular problems, and these are two very complicated games in which we have to be certain." This a clear indication that the Spain coach isn't prepared to take any risks.
However, probed as to whether Costa has a future with Spain, amidst the powerful international emergence of Valencia striker, Paco Alcacer, Del Bosque pointed out:
"This shouldn't create any doubts, because we hold Costa in high esteem. In the same fashion that Alcacer hasn't been available sometimes, such is the same for Costa now."
The hope for Spain is that given a full summer of rest and recovery, followed by a normal and injury-free pre-season with Chelsea, the striker will be back in top shape for September.
During that month, Spain face two crucial EURO 2016 qualifiers against Slovakia and Macedonia, as they bid to reach the tournament finals in France.
Meanwhile, the only Chelsea player to make this latest Spain squad, is midfielder Cesc Fabregas, whilst Cesar Azpilicueta hasn't been considered this time.
