Best Coach Analysis for Indonesia -- 2

I need a well-structured report that compares Frank de Boer, Jesús Casas, Shin Tae-Yong, and Joachim Löw in order to decide who would be the most suitable head coach for Timnas Indonesia. The heart of the study is an evidence-based evaluation of how each manager has lifted the individual skills of players in the teams they handled before.

Please focus on:
• Concrete examples that show measurable or clearly observable improvement in player ability under their tenure—technical refinement, positional versatility, or notable player breakthroughs are all relevant.
• Context around those improvements (league strength, resources available, length of appointment).
• A comparative conclusion that singles out the coach whose track record best matches Indonesia’s current needs.

Use reliable data sources—club archives, FIFA/UEFA reports, reputable sports analytics platforms—and cite them. Present the findings in a concise slide deck (PDF or Google Slides) plus a short executive summary (1-2 pages) that highlights the final recommendation and key reasoning.

I am happy to answer clarifying questions quickly so you can start right away and deliver an insightful, data-driven analysis.
