Because he got a full game against Vicenza possibly? I won't read much into this.
I hope you are Right...I know I am in a minority here, but he remains, by far my favourite striker...not just my favourite...the one player in our ranks who I am confident could score the goals, most likely alongside his old sparring partner DP, to fire us back to Reclaiming OUR scudetto. I am desperately eager to see Trez, a world class finisher, playing in front of a world class creator...Diego. The same goes for seeing what can happen when he plays in front of, or even alongside, little Giovinco...
But Salvatore, I assume, like you have suggested, that he will plat the full game against the Koreans. And then, whoever has performed the strongest, will get the nod against Madrid.
