Samuel Galindo

Arsenal have signed 17-year-old Bolivian midfielder Samuel Galindo from Real America but manager Arsene Wenger intends to send him out on loan. Wenger said: "I'm looking to send him out on loan. We have a few clubs in mind.

"Galindo is a player who has good technique. He's intelligent, 6ft 2in tall, left-footed with good stamina. He is a central midfielder who can give good balls. He has good vision too which we like here."
