Sevilla signed veteran Mexico striker Javier "Chicharito" Hernández on Monday for the next three seasons to reinforce its attack.

The 31-year-old Chicharito is returning to Spain from English club West Ham, for which he scored 16 goals in 58 matches.

Chicharito played for rival Spanish club Real Madrid in 2014-15 on loan from Manchester United.

He will be under coach Julen Lopetegui at Sevilla, which has made a good start to the Spanish league with two wins and a draw.

"I have come to demand more of myself to bring out the best in me," Chicharito said. "I see myself achieving great things with this club."

Sevilla also acquired goalkeeper Yassine Bounou on loan from Girona, while it sent defender Simon Kjaer on loan to Atalanta.
