Dani Alves is urging Barcelona to make the most of Ousmane Dembele while they can, but he also reminded the France forward he has a duty to "defend the shirt" as long as he remains at Camp Nou.
Dembele was strongly linked with a move away from Barca in January after his agent and the club came to an impasse in contract negotiations.
His current deal expires in June, meaning Dembele is already eligible to discuss free transfers with other clubs, though Barca have made no secret of their desire to keep him.
Nevertheless, Joan Laporta claimed Dembele ultimately rejected a transfer to an English club on deadline day, a decision that left the club president somewhat baffled and assuming he already had an agreement with another team for next season.
Laporta accepted it would be up to head coach Xavi whether Dembele was selected for the rest of the season, though Alves seems to think Barca should make use of his talents while they can.
Speaking on Movistar's #Vamos show, Alves said: "This kind of thing happens in football, but as long as he stays at Barca, he has to defend the shirt.
"If he goes at the end of the season, then so be it, but there are still five months left. You have to take advantage of being here.
"One has to be smarter than the situation. We have to think intelligently and take advantage of the fact that we have the player.
"We need unity in the entire locker room. You have to create a healthy environment of positivity, in which there are no bad vibes. If everyone contributes their own, Barca will come back, that is everyone's goal."
Alves returned to Camp Nou in November after leaving Sao Paulo and was eventually able to be registered at the start of 2022.
Three more new signings arrived in January as Ferran Torres, Adama Traore and Pierre-Emerick Aubameyang joined the club.
But due to UEFA regulations only permitting three squad alterations ahead of the knockout phases of its club competitions, one of the new arrivals had to be left off their Europa League list.
Alves was the unfortunate one and, while he acknowledged a degree of frustration at the decision, he insisted he was not about to make a big deal of it.
"The coach knows what I think," he said. "I am always focused on trying to contribute as much as I can.
"We are employees. The club decides. I came to help, to add things, to bring a degree of competitiveness and winning spirit.
"If helping means staying out [of the squad], fine. They are phases of life that one has to accept.
"I would've liked to be in the squad, but unfortunately there were four players for three spots. I'm not going to catch bad vibes, I will continue trying to help."
