FC Basel, under the management of Alexander Frei, has shown both positives and negatives in recent matches. While the defense remains relatively solid, it's the offense that needs more creative impetus. The team has generated numerous scoring opportunities in the last league matches but has often failed to convert these into goals. One reason could be the lack of flexibility in the attack.

One of the first adjustments that should be considered is a shift to a more flexible 4-2-3-1 system. In this setup, the central attacking position could be filled by a playmaker capable of both orchestrating plays and opening space for the wingers. This adjustment could enable the wingers to engage more in the attacks and generate more threat from the flanks.

Furthermore, incorporating more mobility into the attack is crucial. Players like A. Ajeti and M. Cissé should be able to destabilize the opponent's defense through quick combinations and positional interchanges. Increased fluidity in the attack could help the team apply more pressure on the opponent and create more space.

Another important aspect is the utilization of set pieces. FC Basel has won some good free kicks and corners in recent matches, but often lacks the potency and precision in execution. Implementing targeted set-piece strategies that leverage the physical advantages of players in the box could be a valuable source of goals.

Additionally, a return to fluid passing play in midfield should be prioritized. Too often in recent games, the ball has been unnecessarily lost or moved forward too slowly. A quicker ball circulation could not only overwhelm the opponent's defense but also boost the confidence of the offense.

In conclusion, FC Basel has the potential to improve its current form through strategic adjustments and a higher degree of flexibility in its attacking play. It is essential for the players to adapt to the new tactics and be willing to change their roles within the system. With the right tweaks, the team could enhance its offensive power and find the desired consistency.
