Sergio Busquets feels he must take the responsibility for Barcelona’s failure to down Deportivo La Coruna at Camp Nou on Saturday.

The Catalan giants had appeared on course for a routine win thanks to goals from Lionel Messi and Ivan Rakitic but Depor began their fight back on 77 minutes as Lucas Perez reduced the deficit.

Alex Bergantinos grabbed the away side’s second with less than five minutes remaining after Busquets had given the ball away, and the midfielder has shouldered the blame for the dropped points.

“In the second half with 2-0 we thought it was almost done,” the Spain international told Barca TV.

“We had the bad luck of conceding a goal and then my loss of the ball, which I take full blame for the equaliser.

“We must learn to close out games or when we can try to limit any counter-attacks and have plenty of men behind the ball.”

Barcelona will now head out to Japan to compete in the Club World Cup, where they face China’s Guangzhou Evergrande in the semi-finals on Thursday, and Busquets remains in a confident mood despite the stalemate with Depor.

He added: “When we travel and make it to Japan we will compete in the cup with great enthusiasm. It’s an important tie and we will try our best.”

Barcelona are 3.25 to win the Champions League outright, while Spanish rivals Real Madrid and Atletico Madrid are 6.00 and 15.00 respectively.
