Scott Sinclair has made another move in a hope to reignite his career, with the 27-year-old linking up once against with former mentor Brendan Rodgers.
Rodgers managed Sinclair when the pair were at Swansea, as they led the Welsh club to Premier League promotion back in 2011.
After an impressive campaign at the Swans, Sinclair was snapped up by Manchester City, but his career in blue never took off, and was permanently sold to Aston Villa last season.
Sinclair scored six times in 33 matches for Villa but couldn't stop the club from getting relegated.
"It feels amazing to have joined Celtic." Sinclair said.
"It's a massive club and I'm looking forward to it. I'm here now and I'm happy to be here.
"I can't wait to get on the pitch. When I went back to Aston Villa for pre-season, I heard Celtic were interested, and I just knew I had to come here.
"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 pacey winger was delighted to seal the move to Rodgers' Celtic, and is looking for the move to revive his career.
"The manager had a great influence when I was at Swansea and that's when I played my best football," Sinclair added.
"Hopefully now I can get my form back out there and score goals and perform.
"I'm just hoping to come here, score some goals, create chances and hopefully excite the fans."
