There might be a two on two first, later against some E10 members. Most particularly taking some important food culture clubs (max two, unless if the representative resided in PSD means max 3) under ownership of PSD/Yukihira Diner & Trattoria Aldini on each days
Soma is not a type of person to surrender to anything that is non-sensefully evil, that's why he has so many newfound friends to follow (whethere before or after he reveal himself/is revealed by someone who knows Joichiro as Joichiro's son). His main priority behind his pride succeeding his father, is about friendship, unity/bonds, love and peace comes first, even it means he has to sacrifice his pride.

Something ringing my head that Soma might changes his mind of no longer desires to be an Elite Ten due to the recent school situation Azami has turn into - even after Azami is striped from being director, onwards. Remembering about why Momo got 1st place while Tsukasa got 4th + what Rindou said about the seat ranks does not matter like Eizan (if not rigging the match). As a prove that he defeats Terunori (by the time before an unexpected take over by Azami) and Eizan, thus some Elite Ten members he recently up against, especially his past XPs (from failure until find the tricks to solve to new ones; training with the alumus like his parents (prior Soma enters Totsuki) and Shinomiya (during Stagiare)), he'll might realize and believe that he himself "already" an Elite Ten to begin with, just as he believes that his mother (her soul) still with him. Although this action of his becomes a worldwide sensation, and widely known being a non-Elite Ten chef to be a Legendary Alumus, and will graduate
If the bastardly tattoo cross opponent is specialized Norwegian, i bet Soma might goes using Fish (particularly Salmons). Team Up with Takumi will eventually make an Italy-Norwegian Fish (Salmon mainly) dish (either Spaghetti, Lasagna, Fettuccine), with main sauces are tartars and ketchups + some special trick arrow ingredients from their sleeves
