The former Brescia and Racing Santander midfielder told the Washington Times: It was frustrating for me.
"I always want to be on the field; that's what I love to do is play soccer. So waiting here only because you need a signature [was] a little frustrating."
Coach Tom Soehn said his main concern was getting Szetela ready to endure a 90-minute game. So he said the delay didn't create too many problems.
"I think the timing of it was fine," Soehn said. "We had to get him some training before [he played] anyway. You don't ever want to throw someone into the mix too early."
