Athletic Bilbao 0-1 Barcelona

Luis Suarez is starting his first season since 2012-13

Luis Suarez scored and Lionel Messi missed the 14th penalty of his career as Barcelona beat Athletic Bilbao in their La Liga opener.

But the treble winners, who cannot sign players until January, lost full-back Dani Alves and midfielder Sergio Busquets to injury.

Messi's penalty kick was saved by Gorka Iraizoz after Gorka Elustondo was deemed to have fouled Suarez.

After the break, Suarez scored the winner from Jordi Alba's cross.

It was the first time in three years the Uruguayan has been able to start a season following biting bans in the past two years.

Lionel Messi has failed with 22% of his penalties (taken 63, scored 49, missed 14)

But Luis Enrique, who has lost Pedro and Xavi from his squad this summer, will be worried about injuries to right-back Alves and midfielder Busquets.

Barca are not allowed to register Arda Turan or Aleix Vidal, or any other summer signings they make, until January because of a transfer ban,

The game will be seen as revenge for Barcelona, who lost 5-1 to Athletic Bilbao over two legs in the Spanish Super Cup in the past two weeks.

Real Madrid played Sporting Gijon immediately afterwards, and drew their match 0-0.

Atletico Madrid beat Las Palmas 1-0 on Saturday, with Antoine Griezmann scoring the only goal.
