One of the most disappointing aspects of Barce - lona's failure to win major silverware last season was the lack of on-field chemistry between Lionel Messi and Neymar.

Four-time World Player of the Year Messi and Brazil forward Neymar had injury troubles during 2013-14 but when they were fit, Barca fans, expecting the emergence of a lethal partnership scoring goals at will, were largely disappointed.

On the evidence of Saturday's 2-0 La Liga win at home to Athletic Bilbao, however, this season may be a different story.
