MANCHESTER UNITED are to open talks with Nike over a world record new kit deal worth an astonishing £400million.
The US sportswear giants pay £23.5m-a-year to supply the Premier League champions and their current 10-year agreement expires in 2015.
Nike replaced Umbro in 2002 and United have received £303m over the course of the tie-up.
But Florida-based owners the Glazers have seen the deal dwarfed in recent months and want to ensure their club are the top earners again.
A United insider said: "The club have made big efforts on the commercial side over the last 12 months but the kit deal is the real big one.
"The Glazer family are well aware what United's brand is currently worth.
"It's not gone unnoticed that kit deals have been taken to another level since the club entered into our original agreement."
United, whose global stars like Ji-Sung Park and Javier Hernandez help to sell millions of shirts worldwide every year, are well aware they remain the flagship sports franchise for Nike.
Sport of the World understands the club are "delighted" with their on-going relationship with the firm and hope to have something new in place by the middle of next year.
But the Glazers remain focused on paying off debt and could yet be attracted by rival interest should Nike not deliver.
It is believed a new benchmark figure will be closer to £40m a year and rising over the course of a new decade-long deal.
