He became Dinamo's first Argentine signing of the 2009–10 season. He made his competitive debut for the club in the Europa League 2009-10 1st leg tie against FC Lahti.

During his first press conference in Albania Rafael Sosa explained how he was happy with his move to Albania and that although he found it difficult to settle in at a new club which is his first away from Argentina, he would give his 100% for the club. He also stated that he doesn't expect to score many goals, he just wants to play good football for Dinamo for as long as he is there.
