CELTIC striker Jack Aitchison has signed a three-year deal with Barnsley.

The youngster spent last season on loan at Forest Green Rovers in England's fourth tier and has now left Parkhead on a permanent basis to sign for the Championship club.

The 20-year-old will be immediately shipped out to an unnamed club in League Two for the season but Barnsely have included a clause in his contract to recall the forward in January, should they choose to do so.

Aitchison told the Barnsley website: "I was excited to get down here and get the deal done. As soon as I knew there was a chance of coming to Barnsley, I didn't have to think twice.

"This is a good club where I know I'll be able to improve and develop my game."

Barnsley CEO Dane Murphy added: "Jack is a real talent and we’re delighted to have secured his services. He comes with real pedigree, having progressed through the Celtic academy set-up and is hungry to prove himself in England.

“We have no doubt that Jack will play a significant role at Oakwell in the near future, but right now it is vital for his continued development that he plays regular football.

“Jack will spend a period of time in League Two, but we will monitor his progress closely.”
