Lionel Messi celebrates his 33rd birthday on Wednesday and would like to mark it with a win tonight, and his 700th career goal.
The Basques have a terrible recent record at Camp Nou - 14 defeats in a row. However this season they have beaten Barcelona twice, in the first game of the season and in the Copa del Rey.
Messi is aiming at hitting his new goal milestone after not netting against Sevilla. He has 629 for Barca and 70 for Argentina in 721 and 138 games respectively, since October 16, 2004.
