Slovakia winger Weiss started Bolton Wanderers' final three games of the season - and is keen to get more Premier League football under his belt.
"All I can do now is work hard and hope that I get to go to South Africa," he said.
"I've played a few times for my country now, but it would be incredible to go to the World Cup at such a young age.
"I love City and would like to stay there for years - and next season could be very exciting.
"City will need a bigger squad if they are playing in Europe and they will also be looking for some players who've come through the Academy."
