Barça is clear that one of its priorities for this transfer window is to strengthen the left winger position. Despite having Raphinha and Lamine Yamal as starters on the wings, the coaching staff believes there is a lack of depth and alternatives. That's why Flick has requested a player who can compete for a spot and provide imbalance from day one.

Thus, the sporting management is already working to find a profile of a winger who can create imbalance and has the ability to make a difference in one-on-one situations.
Luis Díaz and Rashford, the favorites
Among the names Barça is considering, the most favored is the Colombian Luis Díaz. The Liverpool player is considered the best possible option due to his quality, experience, and fit within the system. Luis has also shown interest in the blaugrana option, although his price and the difficulty of negotiating with Liverpool are two significant obstacles.
As an alternative, Marcus Rashford appears as the most solid plan B. The Englishman has been closely monitored by the club, especially given his situation at Manchester United. If the deal for Luis Díaz doesn't go through, Rashford could become Barça's main target.
Nico Williams, completely ruled out
On the other hand, a name that has been completely ruled out is Nico Williams. The Athletic Club winger was one of the main aspirations last summer, but he ultimately stayed at San Mamés. This time, Barça's offices no longer consider signing him as a real option.

Nico, who keeps a good relationship with some Barça players, such as Lamine Yamal, had been mentioned around the locker room, but there's no real intention to sign him. The club has changed its priorities and doesn't see financial or sporting room to go for him this season.
Rafael Leao also out of the picture
Another player who has definitely dropped off Barça's list is Rafael Leao. The Portuguese was considered an attractive option due to his ability to create imbalance, but his cost, both in salary and transfer fee, has led the sporting management to close the door on his signing. According to El Nacional, the player has lost patience with the Catalan club.

Given the lack of moves from Barça, Leao is now seriously considering an offer from Bayern Munich. The Bavarian side has put a proposal on the table and the Portuguese could accept the German challenge, tired of waiting for a call from Barcelona.
