Barcelona utility Sergi Roberto said he crossed his fingers that superstar captain Lionel Messi would remain at Camp Nou.
Messi stunned the world last month when he informed Barca of his intention to depart the LaLiga giants, with the 33-year-old intending to trigger a clause in his contract to walk away on a free transfer at the end of last season.
However, the validity of such a stipulation was murky due to the campaign being extended by the coronavirus pandemic, and six-time Ballon d'Or winner Messi ultimately opted to remain in Catalonia rather than challenge Barcelona in a legal battle.
Asked about Messi heading into 2020-21, Roberto told RAC1: "I thought the same as all the Catalans, that it could not be true that Messi did not continue with us.
"I cannot imagine a Barca without Leo and I crossed my fingers so that he would stay. I see him training very well. He is a very professional player and I have no doubt that he will always give 100 per cent for this shirt and this club."
Ronald Koeman is at the helm as Barca prepare for their LaLiga opener against Villarreal on Sunday.
Koeman replaced Quique Setien, who was only appointed in January, after Barca were dethroned by bitter rivals Real Madrid in LaLiga and humiliated 8-2 by Bayern Munich in the Champions League quarter-finals last season.
"He [Koeman] has made us work a lot," Roberto said. "The training sessions have been very long.
"We are working very well. He tells the players things clearly and that is good for the team. I fully trust the coach and all the players."
As well as a new coach, there are changes with Barca's playing personnel following Arturo Vidal's move to Inter and Ivan Rakitic's return to Sevilla.
Full-back Nelson Semedo is also poised to join Wolves in the Premier League, while veteran forward Luis Suarez is reportedly in discussions to swap Barca for rivals Atletico Madrid.
"The president or the new coach must decide who they trust and who they will count on," added Roberto.
"I have a special appreciation for Suarez. He is a player who has given a lot all these years. If he ends up leaving, Atletico will be much stronger."
