Puig has since represented the Catalan giants on 56 occasions across all competitions, but the Spaniard is not regarded as a first-team regular by head coach Xavi and has been allowed to seek pastures new in the USA. Speaking to LA Galaxy's official website on the arrival of Puig, head coach Greg Vanney said: "We are pleased to welcome Riqui to the LA Galaxy. Riqui is a very technical and well-educated player with incredible experiences for his age. He will fit seamlessly into our group and style of play. " Puig could make his debut for the Galaxy in their next MLS fixture away at Sporting Kansas City on Saturday. .
