The prompt context mentions "Diogo Costa" then talks about a "Spanish striker" (Diego Costa?), which is an unrelated player. I must focus on *Diogo Costa*, the Portuguese goalkeeper. The provided context is actually slightly distracting/misleading (mentioning a Spanish striker in the context of Diogo Costa). I will ignore the specific context about the Spanish striker and focus on *Diogo Costa*, the goalkeeper, and *Chelsea GK* as the primary keywords. The context about the "big Spanish striker" is likely a copy-paste error from a different piece of text or a deliberately confusing test. My task is to write about **Diogo Costa Chelsea GK**.
