 Although initially considered to be beyond selection to play for the Sweden U21 team (who were leading their European Championship qualifying group at the time) in the June 2010 fixtures against Israel and Montenegro, Guidetti ultimately got his chance to play at this higher level as a replacement for the injured first choice striker Agon Mehmeti.Guidetti accordingly took his place in the Sweden U21 team's starting eleven that manage to win away 1–0 against Israel.Guidetti earnt his next international cap when he was included in the Sweden U19 team rather than the Sweden U21 team because according to Swedish Under-21 national team coach, Jörgen Lennartsson, they had even "greater need" for him back in the younger team.
