I actually think Lukaku would be a great fit in Tuchel’s Bayern team;
Physicality and Strength: Lukaku's physicality and strength could be a great asset to Bayern's attacking play. His ability to hold up the ball and bring others into play, combined with his speed and strength, could help Bayern in their counter-attacking game.
Goal-Scoring Ability: Lukaku has a proven track record of scoring goals at the highest level, both in domestic and international competitions. He has been consistent in front of goal for his various clubs and his national team, which could be a valuable addition to Bayern's attack.
Tactical Flexibility: Lukaku's versatility and tactical adaptability could be crucial for Bayern's system, as he can play as a lone striker, in a two-striker system or as a winger. This could give Bayern more options and flexibility in their attacking play.
Experience and Leadership: Lukaku is a seasoned player with a wealth of experience playing in top-flight leagues such as the Premier League, Serie A, and the UEFA Champions League. This experience and leadership could be valuable for Bayern's younger players and could help to bring the team together.
Age and Potential Resale Value: At 28 years old, Lukaku is still in his prime and could potentially provide Bayern with several years of top-level performance. Additionally, if the move proves successful, Bayern could potentially sell Lukaku in the future for a high transfer fee, making him a potentially lucrative investment.
I think Chelsea missed out on this gem of a player and truly believe he could be a world class striker, just watch his interview about Chelsea, top class professional.
