“The manager had a great influence when I was at Swansea and that’s when I played my best football,” said the former England Under-21 international.“And hopefully now I can get the best football out of me and 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.“I know Kolo Toure and Dedryck Boyata from Manchester City, but I’m sure it’s a great set of lads here and I’ll quickly settle in.”After earning a big-money to move to Manchester City in 2012, the former England U21 international was forced into loan moves to West Brom and Villa in a bid to gain first-team football.A permanent move to Villa Park followed, but relegation to the Championship has led Sinclair to look for a transfer away, with the winger now making the move to Glasgow. Celtic have completed the signing of winger Scott Sinclair from Aston Villa, finally bringing the summer transfer saga to a close.The 27-year-old has signed a four-year deal with the Scottish Premiership champions, joining up with former manager Brendan Rodgers again.The two worked together at Swansea City, where Sinclair enjoyed the most successful spell of his career. Celtic will hope Rodgers can once again get the best out of the winger.“I can’t wait to get on the pitch,” the winger told the club’s website. “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 underwent a medical on Saturday morning and will now join the Hoops ahead of their Champions League play-off qualifier against Hapoel Be’er Sheva later this month.The 27-year-old went straight into Celtic’s squad for their opening Scottish Premiership fixture against Hearts, being named on the bench at Tynecastle.Scott Allan’s loan move to Rotherham United means the former Chelsea, Swansea, Manchester City and Aston Villa player could be added to the squad for the clash later this month.
