"I have been in training with the physio at Carrington for a few days already building up my fitness levels by running and endurance work mostly," Tiatto told City's official website.
"I am ready to fly now and know that this pre-season is an important one for me after the frustrations of last season. Now I want to get as many games as possible under my belt before the big kick off.
"I have the hunger and desire to get back into the squad and would like to play in four or five matches during pre-season and get myself back into the frame."
