Spanish Mikel Arteta, the manager of Arsenal, expressed his happiness with his team's 1-0 victory over Sporting Lisbon in the first leg of the Champions League quarter-finals.

Arteta said: "I am very happy with the away win in the Champions League quarter-finals against a team that hasn't lost at home for a long time, which shows how tough the encounter was."

He continued: "We were aware of the possibility of not scoring, as when we reached the final third we lacked the final touch, and we had to be more precise, quick, and effective to break through their defense."

He added: "We scored a goal that was disallowed, and there were chances where we were close to scoring, but we lacked the decisive pass, and in the end, a magical moment from the decisive players gave us the win."

He continued: "The winning goal was beautiful, and this is the impact needed at this stage of the season, where everyone must make a difference, and that has indeed been achieved."

Regarding the performance of goalkeeper David Raya, he said: "He made two very important saves, and this is what distinguishes the Champions League, where matches are decided in the penalty areas due to the high quality."

He concluded his statements by saying: "At the moment, Raya is delivering amazing and exceptional levels since joining us, and we are very fortunate to have him on the team."
