Griezmann had begun his career playing for hometown club UF Mâcon. While there, he embarked on several trials with professional clubs in order to earn a spot in one of their youth academies, but was rejected because clubs questioned his size and lightweight frame. In 2005, while on trial with Montpellier, Griezmann played in a friendly match against the youth academy of Paris Saint-Germain in Paris, and impressed several clubs, notably Spanish club Real Sociedad, whose scouts were attending the event. Following the match, the club's officials offered Griezmann a one-week trial in San Sebastián, which he accepted. He was later offered a second-week stay at the club. The club then contacted his parents and formally offered the player a youth contract. Griezmann's parents were initially reluctant to have their son move to Spain, but allowed him to make the move after positive reassurances. Given Griezmann spending time at youth level in a Basque club, he is potentially available to play for Athletic Bilbao, in spite of being born and growing up in the non-Basque areas of France.
