Barcelona want to lighten their squad in January to make room for two new signings and to promote some of the players currently in the club's academy.
The reconstruction of Barça's first team began in the summer with seven first-team players moving on but the work does not end there.
Aside from Riqui Puig and Carles Aleña, who will be allowed to leave on loan, Barça are working on selling Junior Firpo, Samuel Umtiti, Matheus Fernandes and Martin Braithwaite.
The most advanced case is Junior, a player that has several offers from Italy and could leave on loan with an option to buy. Inter and Napoli are keen.
Barça don't want to sell for less than 20 million euros because his former side Real Betis are due a percentage of the deal.
Umtiti is still on the market, too, and he would now be willing to open the door to a loan move as he fights to prove his fitness following months on the sidelines.
In the summer, there was interest from various clubs and he had the chance to leave, but no one could match his wage demands and he refused to go.
He knows that Koeman doesn't count on him now, though, and will look for a club where he can recover his form, although his high salary is still complicating things as well as doubts about the knee problem he's had.
Lyon would like to take him back as long as Barça agree to help cover his wages, while Roma are also monitoring the situation.
Matheus Fernandes is perhaps the strangest case. The midfielder will not get chances under Koeman -- and he knows that.
Earlier this year, his advisors rejected to negotiate a loan move when there was interest from Monaco. That led to tension because Barça feel he's been poorly advised and is having his career destroyed. In fact, the club have not even presented him as a first team player officially.
Now the player wants to leave to prove himself. He didn't get many chances while on loan with Real Valladolid and feels he can't spend more time on the sidelines. Barça will help him leave and there could be offers in Spain and Portugal.
Finally, Braithwaite. Barça signed him from Leganes for 18 million euros hoping to sell him again in the summer -- then the pandemic arrived and he didn't have the chance to impress at Euro 2020, which was postponed, with Denmark.
The forward is loathe to leave and believes he will get chances at Barça, but his representatives know they have to look for a new home. And it would be better if he was transferred permanently.
He has a good reputation in the Premier League and Barça hope to get a loan with an obligatory option to buy. Barça feel he must go to make room for Memphis Depay.
