Germany international Miroslav Klose scored five goals in only 40 minutes as Lazio beat Bologna 6-0 in Serie A.
The 34-year-old, who signed in 2011 from Bayern Munich, is the first Lazio player to score five goals in a match.
He is also the first player to score five in the Italian top-flight since 1986, when Roberto Pruzzo achieved the same feat.
Despite the win, Lazio remain in eighth place, 28 points behind Juventus,
who were crowned champions on Sunday.
Who is Roberto Pruzzo?
- He played for Genoa, Roma and Fiorentina and won six caps for Italy.
- While at Roma he won one league title and four Italian Cups. He also scored a goal in the 1984 European Cup Final, when Roma were beaten by Liverpool.
- He remains the only Italian player to have scored five goals in a single Serie A match (Roma v Avellino in 1986)
Klose opened the scoring on 21 minutes, reacting quickly to tap home after Antonio Candreva's strike from range was parried into his path.
Hernanes added a second for the home side, who ended a run of four games without a win, before Klose completed a first-half hat-trick with two goals in three minutes.
His fourth of the afternoon came four minutes after the restart, with a free header from Antonio Candreva's cross, and he turned in a Sergio Floccari pass just after the hour for his fifth and Lazio's sixth.
The German, who is the only player to have scored at least five goals in consecutive World Cups, was eventually replaced after 68 minutes by former Manchester United and Everton striker Louis Saha.
Elsewhere, Edinson Cavani scored his seventh Serie A hat-trick as second-placed Napoli beat Inter Milan 3-1.
The Uruguayan took his league tally for the season to 29 as he helped his side edge closer to confirming their Champions League place.
