Starsport can reveal Etihad bosses are confident of completing a move for Walker once England’s games with Scotland and France have taken place.
Pep Guardiola made Walker one of his main targets six months ago and wants the deal done before the end of this month with signing a right-back a priority for the Spaniard.
The England international, 27, moved to White Hart Lane from Sheffield United in 2009 for £9m and has gone on to become first choice for club and country.
Walker, who has won 25 caps, is currently with Gareth Southgate’s Three Lions squad preparing for Saturday’s World Cup qualifier in Glasgow.
He is a target of a number of clubs, but it is understood he has chosen to join City so he can be closer to his family, who still live in Sheffield.
