Park Ji-sung is confident he has a 'big future' at Manchester United, despite last season's UEFA Champions League heartbreak.
The South Korean was left out of the squad which beat Chelsea on penalities in Moscow - a decision Sir Alex Ferguson has since described as the hardest of his managerial career.
The midfielder subsequently underwent a knee operation, but marked his first Premier League appearance of the season with United's goal in Sunday's 1-1 draw at Chelsea.
He admits being omitted from the Champions League final in May was hard to swallow, but he is determined not to suffer the same fate again.
"It has been a hard time for me," said Park. "I have to show my abilities so I don't suffer that experience again.
"This was a chance to do that and I need to take them because I still believe I have a big future at Manchester United."
Park impressed with his energetic display against Chelsea as he kept Jose Bosingwa in check and he believes he is approaching full fitness.
He added: "I was quite pleased with my performance.
"My fitness is coming back now. I have been in the gym a lot and prepared as much as I can, so I am pretty much recovered."
United will be fined £25,000 for having seven players booked at Stamford Bridge, but Park feels the champions were harshly treated by referee Mike Riley.
"It was unfair," he said.
"The Chelsea players did the same tackles, but the yellow cards went to us. A couple of their men deserved them as well."
