​Photo by Dennis Bresser/BSR Agency/Getty Images Barcelona’s midfield situation has changed considerably over the last few weeks. Frenkie de Jong’s injury has left Hansi Flick with fewer reliable options in the double pivot, while Marc Bernal is still returning from a lengthy layoff and cannot immediately be expected to carry a full workload.Pedri remains an automatic starter and Gavi has proven that he can play alongside him, but the depth behind them suddenly looks far less secure than it did at the beginning of the summer.There have also been rumours that Flick had already begun losing some trust in Frenkie towards the end of last season. The Dutchman reportedly did not manage his previous injury particularly well and continued playing during a World Cup year despite not being fully fit.That was said to have frustrated Flick, who began trusting Gavi more during the closing stages of the campaign. Frenkie has still travelled with the team for pre-season, although some have interpreted that as Flick wanting him to recover under the club’s supervision and, in a way, holding him accountable for how the situation was handled.With Barcelona still expected to complete more business before the transfer window closes, another midfielder may now have become a genuine necessity rather than a luxury.Casadó Opens the DoorMarc Casadó’s potential departure could completely change Barcelona’s approach to the market. Reports suggest the club would be willing to sell him for approximately €40 million, a significant amount for a player who was developed internally and would therefore represent almost pure profit on the books.More importantly, the sale would help Barcelona remain within La Liga’s 1:1 rule, giving the club the ability to reinvest the money into a replacement midfielder.Casadó has proven himself to be a dependable member of the squad, but €40 million would be difficult for Barcelona to reject given their financial situation.Selling him without bringing in another midfielder, however, would leave Flick dangerously short. Pedri and Gavi can form the starting partnership, but Bernal is still finding his rhythm after a long absence and Tommy Marqués is only beginning his transition into the senior team.Tommy is expected to be counted on by Flick and deserves the opportunity to prove himself, but Barcelona should not place too much responsibility on him immediately. There is a difference between giving a talented academy player opportunities and entering an entire season expecting him to cover major minutes in one of the most demanding positions in Flick’s system.A Casadó sale would therefore create both the need and the financial opportunity to sign another midfielder.Trusting La MasiaBarcelona’s youngsters have once again been among the biggest stories of pre-season. An article published two days ago highlighted Ibrahim Diarra, Ebrima Tunkara and Alex González as three academy talents who have particularly impressed the coachi
