Kepa's sentiments were echoed by head coach Mikel Arteta, who believes 'the margin should have been bigger' following their penalty shootout triumph. Speaking to ITV about how the game played out, Arteta said: "I was really happy. Obviously, we are where we wanted to be in the second semi-final in two years. We played against a team that is very difficult to generate chances [against].
"We generated a lot of them, and I think the margin should have been bigger. And when it’s not after 94, 95 minutes at this level, any set piece can cost you, and it cost us."
Arteta, though, did admit that his side's penalties were 'unbelievable' as Arsenal scored all eight spot kicks. "The penalties were unbelievable," the Gunners boss enthused. "Very different, all of them, but the players showed, again, great composure, a lot of personality and quality to score the goals. We executed really well and at the end, Kepa did what he had to do to help us to go through."
