Barca have already agreed an €80m transfer for Newcastle United's Anthony Gordon, while talks are ongoing over signing Marcus Rashford permanently from Manchester United.
LaLiga's 1:1 financial rule has also given Hansi Flick the freedom to spend even more money, and Atletico Madrid forward Julian Alvarez is on their radar.
Alvarez has expressed his desire to leave Atleti, and according to Fabrizio Romano, Barca have sent a €100m proposal to their divisional rivals.
Diego Simeone is under no pressure to sell his talented forward, as his contract has four more years left to run, but it appears the Argentine wants out.
The 26-year-old produced 29 goal involvements in 49 appearances for Simeone's men in 2025/26.
