'Oh my goodness, I don’t know about this,' William laughed.
'It's very kind...This is going to make my football team discussions a lot harder,' the royal added, pointing to the emblazoned 'George' written on the jersey.
Wills has always openly discussed his passion for Aston Villa.
'A long time ago at school I got into football big time,' he previously told the BBC.
'I was looking around for clubs. All my friends at school were either Man United fans or Chelsea fans and I didn’t want to follow the run of the mill teams.
'I wanted to have a team that was more mid-table that could give me more emotional roller coaster moments.'
Following the royal's visit, Sir Gary Verity said: 'I really feel that a royal visit is the icing on the cake of a hugely successful exhibition, and a testament to the success of the exhibition,' noting William's arrival to celebrate the Great Exhibition of the North.
'If you take nothing else from this exhibition, let it be this: our best is ahead of us, not behind, and I know from talking to the Duke that he is passionate about the North doing even better in the future than we have in the past.
'We have in him a great ally for our future success.'
