Now according to journalist Joan Fontes, the veteran midfielder reportedly had issues with the behaviour of two of his Barca team-mates before he left the club. Fontes told Bar Canaletes that Gundogan did not like compatriot and Barcelona captain Marc-Andre ter Stegen's reserved personality as he felt that as the leader of the side, the goalkeeper should have been more vocal in the dressing room. The second player that annoyed him was his former Borussia Dortmund colleague Robert Lewandowski. The star striker's attitude towards young players and his focus on himself rather than helping youngsters in the team bothered the 33-year-old midfielder.
