Atalanta marked their maiden game in the Champions League knockout stages with a resounding 4-1 win over Valencia in the first leg of their last-16 tie at San Siro on Wednesday.
Gian Piero Gasperini's side dominated from the outset against their LaLiga opponents and opened the scoring after 16 minutes, Hans Hateboer claiming his first goal in the competition with a close-range finish.
Josip Ilicic doubled their advantage shortly before the interval with a fine strike, before Remo Freuler curled home a third from long distance in the 57th minute.
Hateboer then claimed a second five minutes later, and while Denis Cheryshev pulled a goal back for Valencia, the Italian side will be supremely confident of finishing off the job in Spain in three weeks' time.
