Rangers boss Gerrard said the Scottish Professional Football League side had competition from multiple teams for the signature of the 20 year old, who has played at left-back and centre-back.

Leicester will be due to receive training compensation when the pre-contract move goes through once the transfer window opens.

"There were a lot of clubs interested in Calvin and for us it's pleasing to secure the services of another young talent," Gerrard said.

"He's a strong and dynamic athlete, who is very much the modern day full-back.

"He will develop further and we are excited to have made another strong addition to our group.

"He's left-footed, physically powerful, enjoys driving forward and is certainly equipped to thrive in the combative nature of Scottish football."
