Arteta will also be disappointed with how his side conceded the three goals, with his defenders allowing far too much space and time for shots from the edge of the area for the first two, and the third coming from a set-piece.

Fabian Hurzeler's side are packed with young talent and have a fearless approach that will cause problems and concern for any side - as both Manchester United and Arsenal found out over the past week.
