La Liga gets underway on Friday evening as Barcelona head to the Basque Country to face Athletic Club at San Mames.
Ernesto Valverde's men earned their eighth league title in 11 seasons back in May and they are favourites once more, having strengthened over the summer with the arrivals of Antoine Griezmann and Frenkie de Jong.
Athletic have made no real signings during the transfer window, limited as they are by their Basque-only policy, but they ended last season strongly and will hope to be pushing for European football once more this term.
