Celtic have completed the signing of Aston Villa winger Scott Sinclair on a four-year-deal.
Sinclair was part of a Villa side that was relegated from the Premier League last season, having joined the club permanently in 2015 following a loan spell from Manchester City.
"It feels amazing to have joined Celtic," Sinclair, who cost a reported £3.5million, said in a statement on the club's official website.
"I had to look at this move and I thought it would be great for me. And because I know the manager and I know what to expect, hopefully I can get off to a flying start.
"The manager had a great influence when I was at Swansea and that's when I played my best football. Hopefully now I can get the best football out of me and get my form back out there and score goals and perform."
A member of the Great Britain team at the London Olympics in 2012 but never capped at senior level by England, he hopes to get a taste of elite European football, should Celtic overcome Hapoel Be'er Sheva of Israel over two legs of their Champions League qualifying play-off.
"I watched the Astana game in midweek and the atmosphere was incredible," he said, referring to a 2-1 home win in the second leg of the third qualifying round against Kazakh opposition.
"To have the possibility of Champions League football excites me and I can't wait to come here and play at Celtic Park and for it to be rocking."
