Jack Charlton died at his home in Northumberland at the weekend aged 85 surrounded by his family.
Mayor Tierney said: “I was really sad to hear of the passing of Jack Charlton at the weekend. He gave us so many happy memories and reasons to celebrate.
“He was a formidable character both on and off the field who established Ireland as a force in world football.
“In return, we adopted him as one of our own.
“Big Jack was a giant of sport who will be remembered fondly in the hearts of all Irish football fans.
“Following requests by the Foyle MP Colum Eastwood and others I have decided to open an online Book of Condolence.
“This will allow the people of Derry City and Strabane District Council to express their sympathy to his family and share their memories and thoughts on this remarkable man, who captured our hearts and put Irish football on a world stage.
“RIP Big Jack.
“Thanks for the memories.”
