Celtic have announced the signing of Aston Villa winger Scott Sinclair on a four-year deal.

The 27-year-old had a medical on Saturday and could go straight into the squad for the Scottish champions' Premiership opener at Hearts on Sunday.

"It feels amazing to have joined Celtic," Sinclair told the official website. "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."

Sinclair was unable to prevent Villa from suffering relegation to the Championship, scoring just two goals in 27 Premier League appearances.
