The report states that Breda want to bolster their attacking options and want to loan the Turkish international.
Unal is currently on loan at the Belgium side Genk and has two goals in 12 appearances. However, Unal has played just two minutes of football in Genk’s last seven games.
Ünal joined City on a £2 million transfer from Bursaspor over the summer but was forced to move abroad on loan due to not getting hold of the necessary work visa requirements.
The Turkish international striker joined Genk on a two-year loan but City have the option to call him back after his first season.
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.
