Andre on the other hand is a strong character and has all round abilities to play according to the team's needs. I'm sure all our young players will have a lot to learn from Bruno and Andre both."
After signing for the Pune franchise, Bruno Arias said. "I am thankful to FC Pune City for providing me a new challenge. Can't wait to join Spanish manager (Antonio) Habas and others at FC Pune City. Fans can expect nothing less than 100 % from me."

On the signings, FC Pune City coach Antonio Habas said: "Bruno always has had a powerful presence, competing for every ball, and putting his opponents under constant pressure. His ability with the ball to navigate it away from the opposition and feed it to the forwards is impeccable. Bikey adds depth to our defensive unit and as and when team needs, he is more than capable of slipping into the role of a midfielder too."
