Express reports 30 clubs were at the Europa League final watching Kasper Dolberg – including opponents Manchester United.
The Ajax youngster's average performance is believed to have deterred some clubs, but that by no means rules out a move for the Dane this summer.
19-year old Dolberg had an otherwise brilliant campaign in Amsterdam, scoring 23 goals from 47 appearances.
Manchester City are also reported to be one of the clubs present at the final.
