LONDON — When Barcelona came from a goal down to beat Sevilla at the Camp Nou on Sunday, it had to work harder for a home win in the Spanish league than it did in its victory at Arsenal a few days earlier in the Champions League.

Barcelona’s president, Josep Maria Bartomeu, said this is what he wants.

His club is on the verge of breaking the Spanish record for most consecutive games without a loss. Sunday’s win tied the record of 34 matches set by Real Madrid in 1989-90. On Thursday, Barcelona can break it when it travels to Rayo Vallecano, and three days later it will play at Eibar in the Basque region.

These are teams that F.C. Barcelona, with its phenomenal front three of Lionel Messi, Luis Suárez and Neymar, are expected to blow away. But Barcelona knows better than to travel to either club and be complacent. Because with the so-called little clubs, whose stands will be filled with fans imploring players to press and force an upset, complacency would be folly.

And, again, Bartomeu hopes to suffer for the points. “We can lose,” the club president said during an interview last week before the Arsenal game. “We lost a lot of titles in the last 10 years, and we have to make La Liga more competitive.”
