莫雷托：要看到莱万加盟米兰存在不止一个很难克服的障碍（莫雷托：莱万转投米兰困难重重，阻碍绝非仅一项）

Considering recent events

I need to keep in mind the knowledge cutoff of October 2024 while addressing events in December 2025 to ensure I'm not missing anything current. There could be recent rumors or updates I might not know about. I should provide a list of potential obstacles like contract issues with Barcelona, age considerations, FFP regulations, and agent commissions. I’ll also ask if the user wants me to check the latest sources, just to be thorough!Analyzing contract extension rumors

I’m considering reports about the player’s contract, which is likely extended until June 2026, with an option for 2027 depending on appearances. There are several obstacles, like current salary and age, as he’ll be 37 in 2025. Also, since he’s Polish and part of the EU, non-EU concerns aren’t an issue. With Milan's attacking roster changes, I acknowledge the complexities here. I should ask if the user needs a source link or translation, especially since they wrote in Chinese.Drafting a brief overview

I’m planning to create a succinct explanation without heavy formatting, possibly using bullets. I’ll include a one-sentence translation and list out 4-5 core obstacles related to the topic. I'll also ask if the user needs me to look up the latest sources or organize more details, such as transfer fees, contract terms, and a comparison of Milan's wage structure. It's important to phrase everything as typical reasons mentioned in the industry to avoid making definitive claims beyond my knowledge cutoff.
