Joe Hart has teased Celtic fans on Instagram with a cryptic 'Let's go' message.

Fans have been speculating when the stopper might appear in Glasgow and the England cap took to social media to snap a photo of himself, apparently on a flight, for supporters to get excited over.

Added to that the 34-year-old wrote: "Let's go", with a smiley and a green love heart emoji.

Hart, formerly of Manchester City and Burnley as well as West Ham, is seen as a solid replacement for the dodgy Vasilis Barkas and Scott Bain, both of whom have been given opportunities already this season without grabbing them.

Goalie has been a priority position for Celts to strengthen and Ange Postecoglou is understood to also still be on the lookout for a right-back and central midfielder, at the very least.
