Mancini enthused: "He's a complete midfielder. He' s young, he needs the best condition and needs four to five months to acclimatise to show his best.
"In the next championship he will become even stronger. We see, however, a great player."
On fellow January signing Xherdan Shaqiri, Mancini added: "He can play both as a winger and as a playmaker. Maybe behind the two strikers he is better.
"For me the most important thing is the attitude of the team."
