There's just over a week until a fresh season gets underway, but Blades fans have yet to get their hands on any of the new replica kits.
The club did, though, release a teaser of this season's home shirt earlier on Tuesday.
The picture showed just the upper part of the new matchday attire, but clearly showed that it has thinner red and white stripes to previous seasons and, in addition, a block of red towards the top.
Unsurprisingly, this fuelled speculation about the design of United's new look, with links understandably being made to La Liga outfit Real Betis' 12/13 home shirt (pictured).
Betis and United have their kits manufactured by Italian sportswear company Macron.No previews of the shorts and socks which compliment this season's home strip have been published as of yet. SUFC are likely to release their new merchandise before Friday's home friendly with Atromitos.
