Arbeloa's Real Madrid: How a season with Mbappe, Vinicius and no tactical identity fell apart

Bayern Munich's 4-3 win at the Allianz Arena on Wednesday night, eliminating Real Madrid 6-4 on aggregate, ended the one competition that was keeping Alvaro Arbeloa's appointment from looking like a complete failure.

La Liga is nine points gone with seven games remaining. The Copa del Rey was surrendered in the first game of Arbeloa's tenure, a 3-2 defeat at second-division Albacete. The Champions League, which finished at full time on Wednesday, was the last thing standing.

It is now gone too, and the person most responsible for how a club of Real Madrid's resources arrived at this point is the 42-year-old with no prior senior management experience who has been running the most famous team in the world for three months.

When Xabi Alonso was dismissed on January 12, Florentino Pérez needed a solution by nightfall. The solution was Arbeloa, who had been coaching Castilla, the club's B team, for six months, having spent five and a half years total inside Valdebebas. He had never managed a professional senior team. He had never worked outside Real Madrid's training complex. The appointment was characterised by most Spanish analysts not as a project but as a placeholder, a familiar face in a disrupted environment while the hierarchy figured out the next proper appointment.

The press conference then was brief. When asked how long his tenure would last, Arbeloa said: “I'll be here as long as Real Madrid want me to be.” That is not the answer of a man who expects to be there in August.

What Arbeloa inherited tactically was a squad built around an unresolved contradiction. Kylian Mbappe and Vinicius Junior are both naturally left-sided forwards who want to cut inside, who both demand the ball around the same area on the pitch, and who both need specific service to function at their best.

Xabi Alonso spent seven months trying to build a system that accommodated both of them without sacrificing defensive structure and was, in the end, sacked partly because the dressing room pushed back against the rigour of his methods. Vinicius, specifically, was reportedly unhappy with the tactical discipline Alonso demanded.

Arbeloa came in with a different philosophy: give the best players freedom, trust in their ability, and let the football sort itself out. Jude Bellingham described the atmosphere shift accurately when he said Arbeloa had found “a balance” by giving players more freedom to move. But what he was also describing, without intending to, was the absence of a structured plan.

The formation has been the visible manifestation of that absence. Arbeloa started with 4-3-3 sensibilities from his academy work, then shifted toward a 4-4-2 in the period where Real Madrid looked their best and most balanced. That was the version with Vinicius and Brahim Diaz as the front two, Mbappe largely benched, and Valverde driving from deep with Tchouameni providing the defensive anchor.

When opposing teams figured out they could double up on Vinicius and sit in compact blocks to cut off supply to Mbappe, Real had no Plan B. Getafe did it. Mallorca did it. Girona did it. Bayern did it at the Bernabéu in the first leg and Madrid had no answer for 90 minutes.

The Mbappe Problem

The Mbappe problem is the central one that neither Alonso nor Arbeloa has solved, and it is the issue that will define whoever comes next. The Frenchman scored 27 goals in the first half of the season, was near-unstoppable in a 4-3 win over Olympiacos and scored the opener in October's 2-1 Clasico victory. He can, when things click, be the difference between winning and losing a match. But his shot conversion rate across his last seven club appearances dropped from 25 percent earlier in the season to four. He has one goal in that stretch.

His discomfort with Arbeloa's methods has been reported internally, the absence of the tactical structure and technical precision of training sessions that Mbappe preferred under Alonso has reportedly left him frustrated.

Meanwhile, Bellingham acknowledged ahead of Wednesday's second leg that the co-existence of two naturally left-sided forwards “can disorganise a bit,” which is a gentle way of saying the team's shape regularly collapses because neither Mbappe nor Vinicius is willing to compromise their preferred position.

Wednesday in Munich showed both what Arbeloa's Madrid can and cannot do. Facing a three-goal aggregate deficit, he picked his most attack-minded XI, accepted the defensive exposure that came with it, and got two goals from Arda Güler before Mbappe's finish made it 3-1 on the night. For about 80 minutes, it nearly worked.

The gamble was tactically logical: a side set up to defend would have lost more heavily. Then Camavinga, brought on as a substitute, got himself sent off for a soft second yellow with four minutes remaining, conceding two late goals as Bayern ruthlessly punished ten men. As reported by Super Sport, Arbeloa called the red card “unbelievable” and said the evening's work had gone down the drain because of a referee's decision. In a sense, he could be right. But it may also be true that a team with better discipline, a more coherent defense and a less predictable attack wouldn't have needed a comeback from 3-1 down with ten men to survive.

So far, Arbeloa has recorded 13 wins, seven losses, one draw. His win percentage is lower than Alonso's. He has lost to Albacete, Getafe, Mallorca, Osasuna, Bayern and Benfica. For a club the size of Real Madrid, with the squad they have, those defeats in domestic competition against mid-table and lower sides is a structural failure of game management that goes beyond individual bad nights.

Alonso's problem was that he had a tactical system the players didn't want to run. Arbeloa's problem is the opposite: he gave the players freedom they wanted, and the lack of system has cost points they had no business losing.
