Mumbai City FC continued to rebuild their squad ahead of Hero Indian Super League Season 3 by confirming the signings of Brazilian youngster Gerson Vieira and Hungarian midfielder Krisztian Vadocz on Wednesday.Technically sound, composed on the ball and a formidable presence, 23-year-old Vieira is certain to bring energy and dynamism to Mumbai’s back-line. The still relatively raw defender has tasted first-team football in both Brazil and Uruguay with Red Bull Brasil and Club Atlético Atenas respectively.Vadocz, on the other hand, will add a wealth of experience to Mumbai City FC’s midfield having plied his trade in Hungary, France, Scotland, the Netherlands, Spain, Denmark, Switzerland and Australia. The 31-year-old also represented FC Pune City in the first season after the Stallions had drafted him in as a replacement for an injured John Goossens, making this his second stint with the Hero ISL. He debuted for Hungary's under-21s and senior side in 2004 and has also scored twice for the national team in 40 appearances.
