3. Gunnar Nordahl, Giuseppe Meazza - Serie A: 17 each (Nordahl 17 with AC Milan & Meazza 17 with Inter Milan)
Cristiano Ronaldo scored his first hat-trick for Juventus recently, meaning that he has now scored hat-tricks with three different clubs in three different leagues.
Serie A has been blessed with some of the best strikers to have graced the game, with heavyweights Juventus, Inter Milan and AC Milan having played host to the best of them all.
Though Francesco Totti, Alessandro Del Piero, Filippo Inzaghi and Luca Toni have been the top scorers in recent memory, they haven't been able to match the exploits of Serie A legends Gunnar Nordahl and Giuseppe Meazza, who had bagged 17 hat-tricks apiece.
Both of the forwards are revered as icons at their clubs, with the latter even been honoured posthumously when San Siro, the principal stadium in his native city of Milan, which is today shared by two of his former clubs, was named Stadio Giuseppe Meazza in his honour on 3 March 1980.
Nordahl managed the impressive tally of 17 trebles with AC Milan in just five years, while Meazza managed the same in nine years. Of the two legendary strikers Rossoneri star Nordahl was more prolific, scoring 224 goals as compared to Meazza's 214 and even holds the record for most Capocannoniere wins, with five to his name and has won the title of pluricapocannoniere, with five successes in five consecutive seasons between 1950 and 1955.
