Reading captain Jem Karacan revealed that the memory of his sides last appearance at Wembley in 2011 still haunts him.
The Championship side were defeated 4-2 by Swansea but Karacan almost equalised when he hit the post.
“I want to go back there on the day and put that right,” Karacan told the Reading Chronicle.
“We got a couple of goals back and then I hit the post which will always stick with me. It was just one of those things.”
Karacan underlined that Reading will try to make amends for the semi-final defeat today as they take on Arsenal at the same stage of the cup.
The Reading captain also stated that his teammates are really looking forward to playing at Wembley.
“It was an incredible day and one of the best occasions I’ve had in football, but my memory always comes back to the disappointing result. There are mixed memories at Wembley but hopefully we can go back there and make amends,” he added.
“It’s a massive day and any chance you get to go to Wembley is a huge occasion. The boys are really looking forward to it.”
The 26-year-old had been out with a cruciate ligament injury but has since recovered and is nearing full match fitness.
The experienced midfielder made his first senior start in 570 days on the weekend in the goalless draw against Blackburn Rovers in the Championship.
Karacan has one goal in seven appearances in all competitions for Reading this season.
