Flamengo Vs Racing Club [1–0] – Copa Libertadores 2025: Full-Backs Shine As Filipe Luís Tactics Edge Tight Semi-Final First Leg – Tactical Analysis

A Copa night, in every sense of the word, opened the semi-finals of the Copa Libertadores.

The Maracanã witnessed the first leg of the semifinal between Filipe Luís’s Flamengo and Gustavo Costas’s Racing Club, two teams with very different paradigms and playing approaches, further contrasted by the context and the stage itself.

Although the final score (1–0) might suggest a tight contest, the match was intense, attractive, and rich in tactics.

The home side, led by an inspired Jorge Carrascal, sought to impose their dominance through possession and initiative.

At the same time, Racing opted for a compact, disciplined mid-to-low block that, at times, frustrated the Brazilians’ offensive attempts.

With Pedro isolated as the central reference, it was the attacking midfielders and full-backs who made the difference for Flamengo in attack.

In contrast, the Argentine side, still unable to find a midfielder capable of adding fluency to their circulation (a role once filled by Juan Fernando Quintero), relied on collective resistance and tactical order.

Costas has built a hard-working, selfless team that came close to taking a more favourable result back to Avellaneda.

In this tactical analysis, we’ll analyse in detail some of the key aspects that defined the match: Flamengo’s constant search through their full-backs, and Racing’s solid mid-block that conditioned much of the game’s flow.

Racing’s Chameleonic Plan

It would not be easy for the Argentines to withstand the creative surge of the Brazilians.

To compensate, Gustavo Costas designed a chameleonic team, capable of defending with either five or four players in the backline, depending on the situation.

It’s not the first time Santiago Sosa, a classic holding midfielder, drops between the centre-backs to act as the last man, follow fixations, or cover depth.

Adding to that versatility was the relentless effort of the wide midfielders.

Both Tomás Conechny and Santiago Solari worked tirelessly to counter Flamengo’s width and depth, which were provided by their full-backs, a key element of their attacking scheme.

Thus, Racing alternated between 4-4-2 and 5-3-2 in their mid-block, adjusting depending on whether an inside midfielder or a wide player dropped back.

The plan was clear: prevent inside turns, maintain density in central areas, and push forward collectively with numerical equality, or even superiority, against Flamengo’s first attacking line.

The coordinated pressing jumps mirrored the team’s lateral shifts, while cover movements ensured stability against runs in behind.

Everything revolved around a single principle: to conquer the interior zones and deny the spaces where Flamengo’s talent usually flows.

Racing Timing & Jumps

Despite the defeat, Racing can feel satisfied with both their plan and execution.

Flamengo struggled immensely to break through the two defensive walls set up by the Argentines during static attacks.

Beyond the result, the consistency of effort, tactical discipline, and collective involvement were remarkable.

The level of individual vigilance, coordination, and pressing timing was elite, preventing players like Giorgian De Arrascaeta or Jorge Carrascal from finding comfort between the lines or in the half-spaces.

Even when the match demanded extra physical effort on top of tactical intelligence, Racing responded immediately.

Man-oriented pursuits were constant: wingers tracking opposing full-backs, and their own full-backs marking inwards on the rival wingers.

Flamengo’s positional rotations could have caused an imbalance in delicate areas, the so-called “undefendable spaces” (half-spaces).

However, Racing’s defensive involvement in long pursuits and cross-coverings neutralized much of that threat.

The final score may leave a bitter taste, but Racing’s tactical execution reflected meticulous preparation and a collective commitment worthy of a continental semifinal.

Flamengo Attracting From The Outside

Racing’s entire defensive design was aimed at protecting the inner corridors.

The main priority was to deny space to De Arrascaeta and Jorginho, preventing them from receiving between the lines or floating through the block.

That part of the plan worked: the mid-block was solid, compact, and difficult to break.

However, the other side of the balance, the full-backs, fell short.

Racing controlled the centre well, but structurally, and by priority, neither Conechny nor Solari tracked Guillermo Varela (right) or Alex Sandro (left) deep into their own half.

The Brazilian full-backs, comfortable in high and wide positions, frequently carried the ball forward, gaining meters and freeing the inner lanes that Racing tried to protect.

When Racing’s midfielders were forced to jump outward to close those lanes, a domino effect was triggered: interior disorganisation, larger gaps between lines, and greater freedom for Flamengo’s creative players.
