Analyzing goalkeeper transfer implications

I should acknowledge the request and ask if they want a brief analysis on background, impacts, tactical aspects, and significance for Arsenal/Newcastle. Ramsdale lost his starting spot to Raya and seeks game time for future England contention. Newcastle needs competition and depth due to previous injuries and European matches. The loan fee is likely around £4m. I should include Ramsdale's strengths and weaknesses, and how he fits into Eddie Howe's style. I'll produce a concise summary with bullet points.
