Raheem Sterling made history by becoming the first player to appear in the UEFA Champions League for four different English clubs after coming on as a substitute in Arsenal's 0-0 draw against Atalanta. Sterling, 29, debuted in the competition for Liverpool in 2014 and later appeared for Manchester City and Chelsea before joining Arsenal on loan. Despite his appearance, Arsenal struggled offensively, with David Raya's double save from a penalty being crucial in securing the draw. Sterling's European experience is expected to benefit the Gunners as they aim for Champions League success. Former Chelsea defender Glen Johnson believes Sterling can thrive under Mikel Arteta's management. Arsenal's next challenge in the Champions League is against Paris Saint-Germain on October 1st.
