Celtic have submitted an offer for Chelsea midfielder Ross Barkley, according to Football Insider.

The Lowdown: Celtic linked with Barkley move

The Hoops' transfer business may not be done just yet, with Ange Postecoglou thought to be chasing one more midfielder and one more attacking option.

Barkley is a player who has been linked with an audacious switch to Parkhead, having been deemed surplus to requirements by Chelsea manager Thomas Tuchel.

The 28-year-old only made one start in the Premier League for the Blues last season, and although some members of the media have claimed a move to Glasgow won't happen, a fresh report suggests it could truly be on.

The Latest: 'Shock' offer

According to Football Insider, Celtic have 'submitted an offer' for Barkley and 'Postecoglou has given the green light to a shock swoop'.

A season-long loan deal for the 33-time capped England international is mooted, and while the Hoops cannot afford his £120,000 per week wages in full, they have offered to 'pay a significant portion' of his salary.

The Verdict: Hugely exciting news

Barkley could be an outstanding signing for Celtic, possessing the technical quality and unpredictability to light up Parkhead with an injection of end product into the attacking midfield ranks.

The former Everton prodigy himself has said in the past that he wants to be considered 'world-class', while Joe Cole has described him as 'fantastic' and a 'top, top' player in the recent past, and although it hasn't worked out at Stamford Bridge there is certainly talent ready to be unleashed.

Barkley has 60 goal contributions to his name in the Premier League and 77 in total for club and country, which is a testament to his class, and at 28, there is no reason why he can't perform at his peak for Celtic this season.
