The Turkish giants suffered a damaging 1-0 defeat at home to Ferencvaros in the first leg of their UEFA Europa League play-off tie.
Having come off the bench against Kasimpasa in the Super Lig last weekend, the former Liverpool superstar was handed his full debut at Papara Park, but even the Egyptian's presence could not prevent his new side from faltering.
Trabzonspor dominated large periods of possession, registering a higher Expected Goals (xG) total from the match, but struggled to dismantle a resilient Ferencvaros setup.
Mo Salah waiting on first win in Trabzonspor colours
Operating on his usual right flank, Salah showed occasional flashes of his trademark quality, cutting inside to test the goalkeeper with a curling effort early in the second half.
However, the Hungarian champions stood firm, frustrating the hosts and proving clinical when their moment arrived.
Former Bristol City and Cardiff City winger Callum O'Dowda featured for the visitors, operating on the same flank as Salah.
With a 1-0 advantage secured on foreign soil, Ferencvaros head back to Budapest as favourites to advance to the Europa League league phase.
For Trabzonspor, the defeat carries consequences that extend beyond the pitch. Failure to overturn the deficit in Hungary next Thursday would see the club drop down to the UEFA Europa Conference League, inflicting a potential financial blow on the club.
Reaching the main stage of the Europa League guarantees participating clubs a baseline starting fee of roughly €4.3m, complemented by broadcast revenues and performance bonuses. In contrast, dropping into Europe’s third-tier competition reduces guaranteed entry fees to approximately €3.17m, alongside vastly reduced television market shares.
For a side that invested heavily to bring Salah to Turkiye, missing out on Europa League revenues represents a deficit they can ill afford.
