Celtic defenders Emilio Izaguirre and Mikael Lustig have signed new deals with the Scottish champions.
The full-backs have been in discussions with Celtic in recent months, and both have agreed three-year contracts.
Izaguirre is currently preparing for the World Cup with Honduras, and he joined Celtic after impressing in the 2010 finals in South Africa.
And the left-back was voted Scotland's Player of the Year in his first season with the club.
The following season, Izaguirre suffered a leg break early in the campaign, and last season the 28-year-old returned to his best form as he picked up his third league winner's medal.
Izaguirre said: "Celtic is a place I have called home for a number of years now and it is the place where I want to be in the future. It is a magnificent football club in a great city, somewhere my family have settled so well.
"I would like to thank the Celtic fans for all the support they have given me over these years and I now want to look forward to many more happy and successful times with these supporters."
Sweden international Lustig joined Celtic in January 2012 from Norwegian side Rosenborg.
While his first few months at the club were punctuated by some niggling injuries, he rose to prominence in his first full campaign, particularly in Europe where he was deployed by former boss Neil Lennon in both central defence and midfield.
Lustig recently returned to action for the Hoops after undergoing a hip operation towards the end of last year.
"I am absolutely delighted to sign this new contract with the club," Lustig said. "Ever since I came to Celtic I have felt welcomed and I have enjoyed every minute of my time here.
"It has been brilliant to win trophies here and I hope we can go again next season and bring more silverware to Celtic and achieve one of our main objectives in the next few months and take Celtic to the Champions League again.
"It is, of course, disappointing that Neil has left the club as manager and obviously all the players wish him all the best for the future. However, I knew that I wanted to be part of Celtic going forward and I am so pleased that I have been able to commit my future to such a great club.
"Like all the other players at Celtic, I will work hard with the new manager and do all I can to bring our fans more and more success."
