The former Aberdeen winger was hotly linked with a move to Forest, but recently signed for Celtic.

Following Jonny Hayes' switch from Aberdeen to Celtic, as reported by BBC Sport, there were few - if any - complaints from one of the sides that he allegedly turned down to sign for the Bhoys, in Championship side Nottingham Forest.
The Aberdeen Evening Express reported that Mark Warburton's side were very much interested in taking the 29-year-old Republic of Ireland international to The City Ground, but Hayes instead opted to stay in Scotland by moving to Celtic.
However, while it may seem like a target missed from a Forest perspective, Hayes choosing Celtic isn't really something that'll aggravate any Forest fan, as there are several reasons why the 29-year-old moving to Glasgow works out better for the Reds.
Firstly, Hayes is 29, and not only is his age a factor, but he's never played in the Championship before - so he would need to adapt and there's no guarantee that he would be able to do so from the get go.

Then you look at how much it would have cost to bring him to Trentside, when really that money could be better off spent elsewhere on the team - especially if Connor Mahoney makes the switch from Blackburn Rovers to Trentside, someone who plays in the same position, is nine years younger than Hayes, and has experience in the Championship.
Hayes may go on to be a brilliant success at Celtic, but when you look at the bigger picture and take all things into consideration, Forest really aren't missing out on anything that major.
