From the official site:
Manchester City is delighted to report that Nissan has today become the Club's Official Automotive Sponsor in a major new deal.
The partnership will see the Japanese automotive giant enjoy a strong brand presence at the Etihad Stadium and on digital platforms, together with the launch of a number of fan engagement opportunities targeting City supporters in Manchester and around the world.
The five year deal, which is the most significant of its type in the Premier League, was announced today at Nissan's global headquarters in Yokohama, Japan.
Most definitely a sign of things to come. City of course took a stake in the J-League side Yokohoma F Marinos a couple of months ago and the deal not just involves City themselves but across the entire 'City Football Group', linking in the City women's team, New York City FC and Melbourne City.
We saw the first signs of symmetry across the group with the announcement that David Villa would spend a short period of time at Melbourne before heading over to New York, the first of perhaps of number of future agreements covering players and coaches alike. Global sponsorship naturally follows this path as City continue to develop and grow since the 2008 takeover.
This AP article reports the deal, over five-years, is worth 'tens of millions of pounds'.
