All you need to know about Junior Alonso, Boca Juniors' first signing for the CONMEBOL Libertadores 2019

The 25-year-old Paraguayan defender arrives from Celta Vigo

Junior Alonso, a Paraguayan defender, is Boca Junior's first signing of the year and joins on an 18-month loan deal with an option to make the move permanent. The 25-year-old footballer arrives after a short stay in Spain with Celta Vigo although he only played in four matches there. Junior Alonso is the man chosen to replace Lisandro Magallán who recently joined Dutch side Ajax.

Alonso began his career with Cerro Porteño before making the move to Europe with French side Lille. Whilst there he worked under Marcelo Bielsa before later moving to Spain with Celta Vigo. At the LaLiga club he met Antonio Mohamed, who is now the coach of Huracán.

Junior Alonso is a physically well built player (185cm tall, weighs 83kg) and is dominant in the air. He's already been capped by Paraguay national team.

"Everyone knows how big Boca are. I'm very happy to come here and when they told me about the possibility of signing, I didn't have any doubts about it," the defender said after landing in Argentina last Saturday.
