Real Madrid defender Pepe says they must improve their concentration after defeat to Sevilla.
The result followed Sunday's El Clasico loss to Barcelona.
"I'd like to congratulate Sevilla; we tried our best to win but it wasn't to be. There are still games to go and we're still in with a chance," said Pepe.
The defender also gave his view on where the match was lost: "We were playing well and putting pressure on them, but it's all about details? We have to be more focused at specific moments and read the game better. We have no margin for error now."
