With Hansi Flick, Barcelona will try to bring in new players, but they also have to keep important names in the team. Flick also needs to know how to keep players who can be important for Barcelona, because it is critical to keep players who play in their own region, such as Yamal, Pedri, Gavi, Ter Stegen, De Jong, in the team. The team may become even weaker because one or more of these players are sent off from the team.
Barcelona needs new players who can help them in this new season achieve quite a lot so they will be able to raise funds from the trophies they are going to win to be able to offset their debts and get the team to be able to get back to their form as they should be, keeping and growing this players too are an important part of what flick should consider doing because these players can and will be very useful to the team in the long term as that have got good form and are still very young cause they have got a whole lot of time on their sides as they are still very young and not looking to have a drop in their performance any soon due to age.
I have always been of the idea that growing a team helps the team get even stronger than it would be if they just go around scout for top players and bring into the team and probably after two seasons max, these players exit the team leaving the team to getting back to scouting for new replacement again. If the players who are very young and are in the team are grown and worked with well enough in other to seeing how they will be able to becoming the kind nod players the team is looking forward to get, the results they will produce too will aswell be same. Yamal, Pedro and joa Felix if maintained are such Young players that will be of a Great assets to Barcelona if they are natured well to become good enough players.
