The Switzerland midfielder was left disappointed with his country's 2-1 loss to South Korea and slammed the performance of the referee after being booked in the first minute
The 20-year-old played all 90 minutes as Switzerland fell to a 2-1 defeat to South Korea at the City of Coventry Stadium on Sunday, leaving their hopes of qualifying for the quarter-final of the tournament in tatters.
Kasami was pleased with his own performance and revealed that he was aiming to win a first-team place with the Cottagers during the coming campaign.
"Hopefully yes [I can play in Fulham's first team]," he told reporters. "I am pleased with my performance today. Now we have the Olympics and after the Olympics I'm going to see what the situation will be.
"It was quite difficult for me, the first season is always difficult. When you're young you need to get the confidence of the coach and if you don't catch the confidence of the coach it can be difficult in your first season in England.
"I think the coach has given a few players chances and hopefully this season I can break through and be a regular and hopefully play every game. But now I have to concentrate on the Olympics."
Kasami was booked in the first minute of the match against the Taegeuk Warriors after jumping for a header with South Korea midfielder Ki Sung-Yueng.
The Celtic star left the pitch on a stretcher but soon returned to the fray and Kasami was angered by what he felt were unbalanced decisions throughout the match.
"I'm not happy with the referee," he said. "I've never seen that in football, a yellow card in the first minute.
"I had about 10 fouls against me and he didn't give them one yellow card [for those fouls]. In the first half, all the time I was on the floor.
"I was very careful [after being booked] because as I said before, the referee was very hard. The first half he gave more fouls to them than to us. It was very difficult.
"I am professional, so I was quite disciplined and I just played my game."
The former Palermo player felt Switzerland were unfortunate to lose the game, and punished by bad luck and excellent finishing.
"I'm not happy with the result," he added. "I thought we played well and had quite good chances.
"We stayed very compact, we were very hard [to break down]. I think the second goal was just stupid, a little bit of luck and it went in."
