Marin has disappeared from Lazio's academy, though itâ€™s understood he's now in Manchester.
Gazzetta dello Sport says City manager Roberto Mancini and assistant Attilio Lombardo had talks with Romanian Marin during the recent youth tournaments in Gubbio and Chianciano.
â€śWe donâ€™t know anything official yet, but itâ€™s clear the lad will no longer be playing with us,â€ť slammed director of sport Igli Tare.
â€śHe can go to City. Mancini acted dishonestly. He couldâ€™ve made a phone call and told us. Thatâ€™s no way to behave.
â€śIn theory we couldâ€™ve signed Marin, but in practical terms we couldnâ€™t, because we wouldâ€™ve had to do the same with another 10 teenagers in our academy. That wouldâ€™ve wrecked the budget.
â€śThe truth is that the current rules on young players in Italy have to be changed.â€ť
