Barcelona’s altered build-up meets Osasuna’s disciplined mid-block

From the outset, the game presented an interesting tactical contrast. Osasuna defended in a 4-4-2 structure out of possession in two different phases of the game. The first one was in the high press, with clear man-oriented tendencies. Their central pairing tracked Barcelona’s advanced midfielders aggressively depending on the side of the ball, effectively closing interior passing lanes and forcing Barcelona into less favorable zones.

Barcelona, meanwhile, built with a back three, as Eric García joined Pau Cubarsí and Gerard Martín in the first line. This adjustment marked a departure from their usual structure, particularly due to García’s more conservative role compared to a typical fullback like Jules Koundé. Gavi operated as the primary pivot, occasionally supported by Pedri, who preferred to position himself behind Osasuna’s midfield line to receive between the lines.

In advanced areas, Dani Olmo floated in the right half-space, while João Cancelo provided width on the left. Fermín López tucked inside alongside Robert Lewandowski, leaving the right flank to be occupied by Rooney, who stretched the pitch horizontally.
