Arsenal manager Mikel Arteta has admitted his side were left seething by the nature of their surprise 3–1 defeat to Real Betis on Wednesday.
A relatively strong starting lineup fell 2–0 down inside 26 minutes and went into the halftime break trailing 3–1. The Gunners dominated possession but were shadows of their usually defensively resolute selves as Betis enjoyed more shots on goal and were excellent value for their victory.
