エディンソン・カバーニ
On 2 February 2009, Italian Serie A club Palermo completed the signing of Hernández, where he joined fellow Uruguayan Edinson Cavani. He was presented by Palermo only one month later, due to some health concerns regarding a cardiac arrhythmia that led to a small surgical intervention. He made his first team debut on 15 March, replacing Edinson Cavani in the final minutes of a 5–2 home win to Lecce. He then won the Trofeo Giacinto Facchetti with the "Primavera" under-19 team in June 2009.
