Former Barcelona sporting director Andoni Zubizarreta has suggested that the Catalan outfit are capable of retaining the Champions League this season.
No team in the modern era has successfully defended the European Cup, but Barca have been tipped by many to lift the trophy once again following their success last season.
Zubizarreta believes that another title is a real possibility and has also backed another of his former teams, Athletic Bilbao, to win the Europa League title.
"Barca and Athletic Bilbao can win the Champions League and Europa League. But it will be very difficult. The group stage is easy when you don't have to play it," Zubizarreta told beIN Sports.
"The Champions League is a very demanding competition. There are other competitions, travel, the knockout rounds. And there are some extraordinary teams in the Premier League, and Juventus and Paris Saint-Germain."
Zubizarreta, who represented Barcelona as a player between 1986 and 1994, was relieved of his sporting director role in January of this year.
