The 61-year-old coach believes that the Camp Nou club will have a hard time to retain their Liga title, while stating the Copa del Rey final deserves the 'best possible venue'
The Catalan giants find themselves 10 points adrift of Real Madrid in the table after suffering a 3-2 defeat against Osasuna at the weekend.
"Madrid are 10 points ahead of Barca, which in times like these is a lot," Del Bosque told reporters.
"But there are still many matches left to play in the competition."
Del Bosque, who revealed last week he plans to retire when his Spain contract expires, was non-committal when asked about the venue of the Copa del Rey final, between Barca and Athletic Bilbao.
"The Copa final is the most attractive match for the players and for the fans, so the best possible venue is what everyone wants," he noted.
"This is a matter for the [Spanish Football] Federation and also of the clubs involved in the game."
