Fredi can take some comfort from at least getting off the mark in his first game of the season, and he says: "I was disappointed with the miss but that is life - it was unlucky for me.
"But I do think it should have been a penalty. Joe is very sharp and skilful and he can make things very difficult when he gets in the box.
"For me, I just want to go through the season without too many injuries because that was my problem last year.
"But I was not very happy at the final whistle on Saturday; we shouldn't have conceded two goals after going two up, even though Arsenal did fight well."
David James says he is happy with the performance on Saturday, but admits of the chance to go 3-1 up: "With all due respect, it was not the greatest penalty in the world."
Glenn Roeder certainly does not condemn Fredi for the penalty which David Seaman saved, and says: "It takes a lot of courage to take a penalty, and he is not the first person in the world to miss one.
"Paolo Di Canio normally takes the penalties of course, but if he doesn't there are two or three others who take them, and it is all about who fancies it on the day.
"There is Fredi, Trevor Sinclair, and Christian Dailly takes a good penalty as well.
"It just depends who is the most confident."
