Adidas optimistic about 2016 though still trails Nike

German sportswear company Adidas says it expects sales and net profit to keep rising fast this year helped by aggressive marketing and big events like the European and Copa America football tournaments and the Olympics.

Adidas reported sales rose 15 percent in the final three months of last year to 4.167 billion euros when it narrowed losses to 44 million euros.

The company is making a comeback after losing ground to larger US rival Nike..

Adidas has fallen into third place in the key US market behind Nike and fast-growing Under Armour and seen Nike threaten its dominance in football and western Europe.

In response, Adidas has closed stores in Russia and boosted its marketing spending, particularly in US sports. Recent coups include replacing Nike as a kit supplier to football clubs including Manchester United.
