The 18-year-old left-back will be eligible to feature for the MLS club once the league's transfer window opens on 8 July, having joined on a season-long loan.
Tasende, known as Angelino, has joined NYCFC on loan for the remainder of the 2015 MLS season and will likely provide competition for Jeb Brovsky and Chris Wingert at left-back during his time in New York.
The 18-year-old Spaniard is the second City player to make the move to Yankee Stadium, with fellow defender Shay Facey joining the club in March, and he believes that his stateside stint will prove a huge help towards his development.
“I’m very happy for the opportunity that Manchester City and New York City FC have given me,” said Angelino. “To be able to play in New York is a great opportunity for me and I am eager to get started. I can’t wait to get to New York and join my new teammates.
“I know Shay Facey is doing really well for the team and loving the experience. The atmosphere at Yankee Stadium seems amazing so I’m really looking forward to playing in front of our supporters.
“Being able to train and play in a professional league like MLS, and learn from Coach Kreis will help me develop further as a young player. I’m determined to make the most of my opportunity and give everything I can to help the team in our first season.”
Angelino first joined the Citizens from Deportivo La Coruna in the summer of 2013, having turned down lucrative offers from both Barcelona and Real Madrid, and earned his Under-21s debut before even turning 17.
The former Under-17 international made 20 appearances for Patrick Vieira’s Elite Development Squad last season, while scoring four goals, and showcased his attacking qualities with a hat-trick in April’s 4-2 win over Leicester.
Moving to NYCFC at the same time as former Spain right-back Andoni Iraola, their arrivals add some much-needed reinforcements to the club’s backline, after a slow start to their inaugural campaign as seen head coach Jason Kreis recycle through defensive options.
While on their first-ever winning streak after victories over the Philadelphia Union and Montreal Impact, the expansion franchise still sit bottom of the Eastern Conference after 14 games, having amassed three wins, five draws and seven defeats.
Whether Angelino will get extended time to help change their fortunes remains to be seen but, with the two Spanish defenders now on board, captain David Villa starting to hit form and Frank Lampard arriving this summer, it looks like the second half of the season could prove much more fruitful than the first.
