The Spaniard was disappointed to see his side fail to hold to a 1-0 advantage in the first leg of the Europa League quarter-final tie.
Mikel Arteta bemoaned Arsenal’s missed chances after a 1-1 draw with Slavia Prague on Thursday night, while admitting that the “final result leaves a difficult taste”.
Arsenal saw Nicolas Pepe’s 86th-minute opener cancelled out in the last seconds of the Europa League clash at Emirates Stadium, with Tomas Holes scoring an all-important away goal for the visitors.
The Gunners will now have to beat Slavia in the Czech Republic to qualify for the semi-finals, and Arteta feels his team missed a good opportunity to establish an advantage in the last-eight tie.
