Jonny Hayes has spent five seasons at Aberdeen
Celtic FC have signed 29-year-old Irish winger Jonny Hayes on a three-year deal.
Hayes links up the Hoops having spent five seasons with Aberdeen. He has also worked alongside Celtic manager Brendan Rodgers in the past.
He previously spent three years with Inverness Caley Thistle as well as a stint at Pittodrie before moving to Aberdeen.
Celtic have just finished an incredible season in which they remained unbeaten on the way to clinching the domestic treble.
Hayes scored the opening goal of the Scottish Cup between Aberdeen and Celtic in May, before Celtic struck back with two goals to secure the title.
Speaking to the Celtic website, Hayes said he was thrilled about the move:
"This is a huge honour for me. It is a dream come true to be part of this brilliant football club and I can't wait to get started.
"I'm delighted. It's been in the pipeline for a little while now but I’m pleased to finally get here. I was eager to get it over the line for the last few weeks.
"Celtic have done well over the last few seasons and with the manager coming in last year he raised the level again. It was hard last year seeing all the celebrations and all the stuff on social media and you want that for yourself and to be part of it.
"Now it's my chance and hopefully, going forward, I can create my own little bit of history and take the chance I've been given."
Hayes added that he's excited about the prospect of experiencing Champions League football with the Glasgow side:
"I can't wait to get back training. Once everything was signed off, I said to Tim Williamson (Celtic physio) that I was just looking forward to that first day in training and getting started.
"You can't get away from the Champions League. I can imagine it is the reason many players have wanted to come here. Not only is it the size and stature of the club, Champions League nights and the atmosphere are a massive factor in wanting to come here.
"Whether you're a football fan or not, everybody knows about the atmosphere of Champions League nights at Celtic Park. I'd be lying if I said I didn't want a part of that."
