The young striker spent pre-season training with city along the likes of Vincent Kompany and Kun Aguero.
“After a mistake you are given support and praise. They try to keep mentally up in every way.” Ünal was quoted as saying by the Manchester Evening News.
“For example, you can make a hard tackle against the captain Kompany but he doesn’t say anything to you and carries on focusing on his job only.
“You don’t expect that somebody will come for revenge later in training. The most important part is the relaxed mood of all players in all age groups. They are giving their best on the pitch and know how to have fun when they not working.”
The Turkish international joined City on a £2 million move over the summer transfer window but was loaned out to Belgium side Genk on a two-year deal.
Ünal has made three appearances for the Belgium top-tier side this season playing a total of 115 minutes.
Despite being 18-year-old Ünal already has an international cap for the senior Turkish national team and is currently on national duty with the U21 side.
Ünal is rated as one of the brightest prospects in Turkish football and currently holds the record as being the youngest player to have ever scored in the Super League aged just 16 against Galatasaray in 2013.
