Nils Mortimer, born in Málaga 19 years ago, arrived at Barça in 2013 from Málaga CF to live in the Masia Residence - Oriol Tort Training Center and play in Marcel Sans' U14B team, who were eventually proclaimed league champion. He has played in all of Barça's youth teams, winning league titles with U16B (2015/16), U16A (2016/17), U19B (2017 / 18) and U19A (2019/20). In the 2017/18 season he took part in the Final Four in Nyon where U19A won the second UEFA Youth League in its history, beating Manchester City in the semi-finals (5-4) and Chelsea in the final (3-0). His profile is that of a very fast, brave left winger, with a very good shot and arrival into the box, as well as a very good ability to unbalance defences. This season he has played 1,301 minutes with Franc Artiga's U19A team and has scored seven goals. In the UEFA Youth League he played all six matches in the first phase, scoring two goals against Slavia Prague.
Nils made his Barça B debut, under the guidance of Garcia Pimienta, on March 24, 2019 in a Segunda División B league match at Ebro, which Barça won 0-1. An international in all of the Spanish youth teams, he competed in the U17 European Championship which was held in 2018 in England and where Spain lost in the quarterfinals against Belgium. In the 2019/20 season, he was a regular in Barça B's squads and played in away matches at Badalona (0-2), Hercules (4-1), Ejea (1-0) and Orihuela (0-0), as well as home games against Villarreal B (2-3) and Llagostera (3-2). He also played against Badajoz and Sabadell in the Play-offs for promotion to the Segunda División A.
Nils is a quick, thoroughbred winger, able to unbalance the best defenders. He has excellent technique and a good ability to associate with his team-mates.
