One option is to use a more traditional midfielder to improve control of possession. Another is to select an additional attacker and rely on movement between the forward positions to compensate for the missing creativity.
The right decision will depend on the opponent and the available players.
Could the injury affect Barcelona's season?
A month on the sidelines could mean Olmo misses several important fixtures. Barcelona must therefore avoid putting unnecessary pressure on him to return before he is ready.
Muscle injuries can be complicated, especially when players are required to perform repeated high-intensity movements. A premature comeback could increase the risk of another setback.
Our analysis: Olmo's absence presents Flick with an opportunity to develop alternative attacking combinations. However, the manager must ensure that tactical adjustments do not make Barcelona too predictable or reduce their ability to create chances against organised defences.
Barcelona have enough technical quality to remain competitive, but Olmo's return will be important as the season progresses.
