Poyet was less than impressed with his side's capitulation which was far from ideal preparation for their upcoming Wembley date against Manchester City.
"I am not accepting this defeat. We were poor in many ways and were second best in everything, Santiago (Vergini) was not the only one," the Uruguayan said.
Poyet continued: "Now no-one has put themselves on the teamsheet for next week, they all had a great chance to show me, but everything I had in mind went in 90 minutes. Now I have to start from zero.
"Arsenal proved again that they can beat anyone, but sometimes players pick the team for you, but now I have a few options for Wembley.
"There are plenty of similarities between the way Arsenal and Manchester city play for me to ponder on."
