Juventus bound midfielder Aaron Ramsey provided a glimpse at the next-generation of adidas Nemeziz in training this afternoon as Arsenal made their final preparations ahead of the North London Derby with Tottenham at Wembley on Saturday lunchtime.

The Welshman was sporting a completely blacked-out out pair of adidas Nemeziz 19.1 football boots, becoming the first player to reveal the laced, next-generation design. Ramsey has worn almost every adidas silo this season to date; he began the campaign in the Predator, before a brief stint in the X series and more recently opted for the Nemeziz "Exhibit Pack" colourway.

Ramsey, previously of New Balance, will bring his adidas ties even closer when he signs for adidas partnered club Juventus in the summer. For now though his priorities lie with The Gunners, although this is a boot he may not even pair up with his Arsenal kit, if adidas decide to launch the new 19.1 in the summer rather than spring.

It ain't too difficult to establish that this is the next-generation of adidas Nemeziz technology – mainly because the word 'Nemeziz' is clearly visible on the instep of Ramsey's boots, but the blackout does keep us guessing on potential launch colourways at least.

Inter Milan's Antonio Candreva has also been testing the next Nemeziz this week, with the midfielder slipping on the laceless 19+ editions. Ramsey's 19.1 boots look to have a slightly lower mid-cut collar than the laceless design and with that comes a cleaner upper that features a less obvious bandage-styled design. As with Candreva's blackouts the 19.1 appears to incorporate a new heel counter and soleplate upgrade.
