Several second-division clubs are interested in Aaron Keller. There are also inquiries from Bundesliga clubs, who would immediately loan him out if they were to sign him. Grasshoppers are also monitoring the situation.
His loan spell at second-division side Ulm ends at the end of the season. The 20-y/o talented winger can leave his contract at Unterhaching (running until 2026) in the summer due to a release clause of around €1-1.5m.
