Rangers' kit manufacturers Castore have agreed a deal with Newcastle United to become their new suppliers, according to reports.

The Liverpool-based brand have been looking to expand their portfolio of football clubs after signing a £25million deal with Rangers earlier this year. The sportswear company revealed at the time of their multi-year deal with the Ibrox club that they wanted to partner up with more of the top clubs in the world.

Now, according to Sportcal.com, Beahon brothers Tom and Phil - Castore's co-founders - have penned a deal with the Geordie club. Newcastle are reportedly set to ditch Puma for the new manufacturer.

Castore have been approached for comment by Herald and Times Sport.

Newcastle, of course, are owned by former Rangers shareholder Mike Ashley who has been embroiled in court battles with the Light Blues for a number of years over merchandising. The Sports Direct tycoon was one of the main reasons Gers supporters had boycotted buying their club's kits in the past, until Castore took over. Since then there have been record-breaking sale numbers.

Meanwhile, Castore's newest Rangers store is set to open tomorrow in Buchanan Galleris. And the brand also unveiled new retro Ibrox kits that will be worn by the players at some stage this campaign.
