The Spurs ace has already voiced concerns surrounding his future at White Hart Lane, with the Belgian international desperate to play Champions League football.
After an up and down season in North London, it looks unlikely that the Lilywhites will force their way into the top four between now and the end of the campaign, which has opened the door for Vertonghen’s possible exit.
City are rumoured to be interested, and a move for him has been given the green light by influential captain Kompany.
The commanding defender plays alongside the Tottenham man at international level, and is believed to be keen to extend that relationship to everyday club life.
City are known to be looking to draft in a partner for their first choice enforcer, and see placing him alongside Vertonghen as a wise idea.
Spurs chairman Daniel Levy is known to be a tough negotiator, but Etihad Stadium chiefs are confident that a deal can be done.
Vertonghen only moved to England from Ajax in 2012, and was named in the PFA team of the season after a fine debut campaign.
