Celtic have completed the signing of Hibs midfielder Scott Brown for a fee in the region of £4.4m - a record between Scottish clubs.
Scott Brown opted to join Celtic instead of the Premiership
The 21-year-old has signed a five-year contract with the SPL champions and said he was delighted to join "one of the biggest names in football".
Rangers, Middlesbrough, Tottenham and Everton were also chasing Brown.
Celtic manager Gordon Strachan told the club website: "Scott has the attributes to be a great Celtic player."
Brown said he was aiming to help Celtic to honours next season and to make an impact in the Champions League.
"The opportunity to join a club of Celtic's stature was one I had to take," he said.
The club has a magnificent support and I will be doing all I can to play my part in delivering more success to these fans
"Celtic has enjoyed a great season, lifting the SPL Championship and making great progress in Europe.
"The club has a magnificent support and I will be doing all I can to make sure I play my part in delivering more and more success to these fans."
The Scotland midfielder thanked Hibs and their fans for their support during his time at Easter Road.
Strachan said Brown would bolster his squad, adding: "We are delighted to have signed Scott and are excited about him joining us next season.
"I'm sure he'll enjoy teaming up with the other players at the club as we try to bring more success to our supporters.
"I would also like to thank the board for their support in bringing Scott to Celtic."
Celtic chief executive Peter Lawwell described Brown as the most talented player in the country.
"Scott did have more lucrative offers elsewhere, but we are clearly very pleased that he has chosen to join Celtic," Lawwell added.
Hibs chairman Rod Petrie revealed Brown had given up a portion of the transfer fee so that the club's youth development programme would benefit.
Hibs manager John Collins paid tribute to Brown and said he had been a "fantastic player" for the Edinburgh club.
Collins told the club website: "He has done everything we asked of him and more, and played a big part in delivering our first trophy for 16 years.
"I am sure the fans will give him a great send-off."
Brown is expected to play for Hibs against Celtic in the final SPL game of the season at Easter Road on Sunday.
