Sebas Mendez, Ecuador
Stats: 4 minutes played
Well, it wasn't a particularly active window for Sebas Mendez, playing just a cameo role in a match against Brazil then not featuring against Peru, but it's an incredibly exciting time for his national team.
Ecuador are currently third in CONMEBOL qualifying and could've clinched a spot in the World Cup with a win against Peru (they drew 1-1). They didn't appear in the 2018 World Cup, but a promising group of youngsters including Moises Caicedo, Pervis Estupinan and Gonzalo Plata has revitalized the national team and has catapulted them up the South American soccer hierarchy. If Ecuador can finish the job, as they likely will next window, it'll be a fantastic opportunity for Sebas Mendez and the young core of players in Ecuador.
