It has been reported that Southampton have agreed an initial fee of £10m with City for Gunn, who spent the 2017-18 campaign on loan at Norwich City in the Championship.
The report has also stated there will be a fee of £3.5m in add-ons, and that the goalkeeper will move to Southampton after passing a medical and agreeing personal terms.
Bargain signing for Southampton?
Gunn has failed to make a single appearance in the Premier League for City, but the goalkeeper showed his class at Norwich last season.
The 22-year-old Englishman was one of the best goalkeepers in the Championship, and he will be expected to establish himself in Mark Hughes’s starting lineup rightaway.
Brilliant at stopping shots and able to dominate his penalty area, Gunn could prove to be a bargain signing for Southampton in the long run, and working with a quality manager like Mark Hughes is only going to make him better.
