Probably Cazorla. Arteta is our first choice , but tbh I did not like his penalties, too risky. Poldi is OK, but too much history involving him and Bayern. having said that I am fine with all three. But please not Giroud. Too much pressure to score on his shoulders.
Podolski Podolski Podolski In high pressure games penalty takers with decisive powerful shots that aren't too concerned with perfect corner placement fare better IMO.
Never trusted Arteta with a penalty at Everton, especially towards the end they were getting worse and worse (and corners and free kicks too). Thank god we have Leighton Baines. Anyway I think Podolski should take them for you.
Arteta's not a bad penalty taker but Podolski strikes a ball better than anyone in our side. He would be my choice.
I'm going to agree with the majority here and go with Podolski. He was a perfect 5/5 from the spot during his last 2 seasons in the Bundesliga.
