Antonio Rudiger is frustrated that his side didn't finish off Arsenal when they had the chance in their International Champions Cup match in Dublin, as the Gunners won on penalties after a late Alexandre Lacazette equaliser.
The Germany international had opened the scoring in the fifth minute but saw his side miss a hat full of chances, including an Alvaro Morata penalty, as they dominated the first half.
Arsenal grew in confidence in the second half and the 1-1 draw saw the game head to penalties. Petr Cech saved from Ruben Loftus-Cheek and Alex Iwobi scored the decisive penalty.
