Celtic has fended off interest in 18-year old winger Michael Johnston by resigning the Scotsman till June 2020.

The Scotland Under-19 international has recently been caught on the radar of clubs in England, most notably, Chelsea.

Speaking after his full-team debut in the Bhoys 4-1 victory over St. Johnstone on Saturday, Johnston said he knew what was happening: "It was literally straight after the final whistle. Once I got changed, I went straight in and got the deal signed.

"I knew it was happening and it all came on the right day."

"I have committed my future here for a reason. This is where I want to be and, hopefully, I can get many more appearances under my belt."
