The 28-year-old gained his first experience as a youth coach during his time on a Sports Studies course in Barcelona and that included being at the Spanish third division club Unió Esportiva Cornellà. After completing postgraduate studies (Education and Sports Management) Sergi Runge moved on to one of the top clubs in Costa Rica: He was assistant to the first team coach at Liga Deportiva Alajuelense and also head coach of the U17 side.
After a year in Central America, he followed the call to La Masia and started at Barcelona in the summer of 2020. Runge, who speaks fluent German and English in addition to Spanish, this week started working alongside Thomas Zdebel on the coaching staff of the Leverkusen U17s.

Roberto Pätzold's team have fled the cold to the south and are preparing for the second half of the season at a training camp in the Algarve, almost 2,000 kilometres away from home as the crow flies. The Leverkusen squad landed in Faro on Saturday morning and have already completed the first three training sessions over the weekend.
