Looking into Szczesny's situation

I want to respond with a concise English translation and a brief context about Szczesny, mentioning that he’s a Polish goalkeeper linked to Barcelona. According to Polish media, before joining Barça, he considered playing in a seventh-division league to stay fit. I’ll keep it straightforward and then ask the user what they’d like: a summary, source link, background on Polish league tiers, career timeline, or social reactions. Let’s keep it short and helpful!
