In the past two turbulent seasons, Barcelona have been forced to promote a large number of young players, and as of now, the team has played under the U21 with as many as 13 players, making it the team with the most young players in the entire La Liga. It is also thanks to their strong promotion that Barcelona have found many treasures in their own youth training system. It is reported that Barcelona are interested in sending away right-back Mingeza, who has lost his position, and promoting midfielder Nick Gonzalez to ease the current employment problem.

At the beginning of the season, Barcelona suffered a serious wave of injuries, which at one point left the first team unusable, so it promoted excellent youth players such as Nico Gonzalez, Garvey, Abde and Uglat.
According to journalist Adrià Albets, Barca are registering Nico Gonzalez into the first team, and they are confident they will finish within this week. Nico is currently registered with Barça B, and so far this season, the midfielder has made 24 appearances for Barca's first team, scoring 2 goals and providing 2 assists. Due to registration with team B, there are restrictions on playing for Nico Gonzalez, as La Liga requires that at least 7 first-team players must be present in the game.
Technically, Nico Gonzalez is one of the few players in the Barca midfield who has both a body and a ball dealer, and can not only send threatening passes in the game, but also use his physical advantage to increase the interception and defensive intensity of the midfield, so promoting him is an extremely crucial decision for Barcelona to qualify for the Champions League.
In addition to promoting nico González, Barcelona also intend to loan right-back Mingeza in the winter window, this player has played average this season and does not meet the positioning of head coach Xavi for right-back, so the player's rental is likely to be completed in the near future.
According to the famous journalist Romano, Valencia intends to loan players until the end of the season, as to whether to add a buyout clause to the loan contract and the proportion of wages borne by both sides is still under negotiation, if the players themselves have no objections, there will be an answer in the short term.
For Barcelona in the blood change period, the back and forth is really not surprising, including the team's strikers Depay and Dembele may also leave in the near future, perhaps until the transfer window closes, we can see the new Barca.
