World Cup 2026: Algeria’s convincing win highlights both strengths and concerns for Vladimir Petkovic

Algeria’s 4-0 victory over Bolivia offered further evidence of Vladimir Petkovic’s ability to influence matches from the touchline, but it also exposed concerns that could prove costly when the World Cup begins.

The Desert Foxes produced two contrasting performances in Kansas City.

A subdued first half gave way to a far more convincing display after the break, with Algeria scoring four goals and ending their preparations for the 2026 World Cup on a high.

While the result was impressive, the manner in which it was achieved has reignited debate over Algeria’s approach from the opening whistle.

Once again, it was the coach’s interventions and second-half changes that transformed the team’s performance.

The pattern has become increasingly familiar.

Against Bolivia, the players introduced after half-time made a decisive impact. Amine Gouiri and Anis Hadj Moussa both found the net, while Adil Boulbina and Ramiz Zerrouki contributed assists as Algeria took complete control of the contest after the interval.

The substitutions changed the rhythm of the match and provided the attacking spark that had been missing during a difficult first half.

It was not the first time Petkovic’s in-game decisions had altered the course of a match. Similar praise followed Algeria’s victory over the Netherlands on 3 June, when tactical adjustments helped the team secure a positive result.

The coach’s ability to identify problems and react effectively has become one of the most reassuring aspects of his tenure. When Algeria struggle, there is often confidence that solutions can be found from the bench.

However, that strength also raises an important question.

If the winning formula repeatedly arrives after substitutions are made, why are those solutions not always present from the start?

Observers have frequently pointed to Petkovic’s preference for certain players or roles that do not always appear to bring the best out of the team. At times, players are deployed in positions where they seem less effective. On other occasions, familiar selections continue to be favoured despite inconsistent displays.

More often than not, the coach eventually finds the right combination as the match progresses.

The concern is whether future opponents will allow Algeria enough time to recover if the initial plan fails.

That issue remains fresh in the memory because Algeria have already experienced situations where they were unable to turn a match around.

The quarter-final defeat to Nigeria at the 2025 Africa Cup of Nations serves as a notable example. During that encounter, Ibrahim Maza and his team-mates never managed to regain control of the game and were ultimately eliminated without registering a shot on target.

The match highlighted the danger of falling behind against strong opposition and relying on later adjustments to rescue the situation.

Such concerns become even more significant with Argentina waiting on the horizon.

The reigning world champions will provide a far sterner examination than Bolivia and represent the next major challenge facing the Algerian national team.

Although Algeria have completed their warm-up programme with two victories, five goals scored and none conceded, there remains a belief that the defensive record does not tell the whole story.

Against the Netherlands, the back line came under significant pressure and benefited from the Dutch side’s lack of precision in front of goal. While Algeria emerged with a positive result, there were moments when the defence appeared vulnerable.

Argentina possess a different level of attacking quality.

With players such as Lautaro Martinez, Julian Alvarez and Lionel Messi available, opportunities are unlikely to be wasted as frequently. Any defensive lapses or tactical uncertainty could be punished quickly.

That reality increases the importance of getting the starting approach right from the beginning.

Against elite opposition, there may be little time to identify problems, make corrections and regain control. A slow start could allow the match to drift beyond reach before adjustments have the desired effect.

This is why Algeria’s recent performances have generated both optimism and caution.

On one hand, the team has won its final two preparation matches, scored freely and maintained an impressive defensive record. The squad also appears to possess strong depth, with substitutes repeatedly making important contributions.

On the other hand, the performances themselves have not always matched the quality of the results.

The first-half display against Bolivia was far from convincing, and previous matches have revealed similar inconsistencies. While Petkovic deserves credit for his ability to react, the challenge now is to ensure those reactions are no longer required.

As the World Cup approaches, Algeria can take confidence from its results and the impact of its squad depth. Yet the coming matches will demand a higher level of consistency from the first whistle.

Petkovic’s tactical flexibility has become one of Algeria’s greatest strengths. Whether that strength continues to compensate for slow starts against stronger opponents could play a significant role in determining how far the Desert Foxes progress in the tournament.
