Egypt and FC Basel striker Mohamed Salah was dealt a stunning 0-3 defeat at the hands of ninth-placed Luzern Sunday afternoon in day 29 of Switzerland's Super League.
With 57 points, the league runners-up failed to make use of the Grasshoppers' 0-2 defeat against Thun on Saturday, with the point differential remaining at six.
The 20-year-old Egyptian came as a substitute in the 63rd minute while fellow Egyptian Mohamed El-Neny was left off the game's squad.
Luzern's three goals were scored by Daniel Gygax (14th minute), Xavier Hochstrasser (44th minute) and Jerome Thiesson (70th minute).
A promising international forward, Salah has been one of Basel's key players this term. He scored five Swiss League goals, with the team remaining on course to retain their title.
He helped Swiss side Basel knock Tottenham out of the Europa League quarter-finals after giving several strong performances.
He impressed in the first leg with his roving runs and catchy feints before finding the net in the return leg, as Basel advanced after beating Tottenham 4-1 on penalties following a 2-2 aggregate draw.
Basel were defeated 2-1 by Chelsea in the first leg of the semi-finals last week. The next leg will be on Thursday.
