Ex-Manchester City Goalkeeper, Hart has completed his shock move to Tottenham Hotspur on a free transfer following his release from Burnley at the end of last season.
The former England international, 33, underwent his medical tests on Monday and has signed a two-year contract that will see him earn £50,000 a week.
He becomes Tottenham’s second signing of the summer after Pierre-Emile Hojbjerg, who joined the club for £15 million from Southampton.
Hart will compete with Paulo Gazzaniga for Hugo Lloris’ No 1 spot in Jose Mourinho’s squad next season.
During 12 years at Manchester City, Hart won two Premier League titles, two League Cups and an FA Cup.
He also enjoyed loan spells at Torino and West Ham before joining Burnley in 2018, where he made 24 appearances.
Hart, who started his career at Shrewsbury, has 75 caps for England.
A former regular for England at Under-21 level, Hart made his senior international debut in June 2008 and was recognised as England’s first-choice goalkeeper from 2010 to 2017.
He has gained over 70 caps and was selected in England’s squads for two FIFA World Cups and as many UEFA European Championships.
