Ricketts, who has made 11 appearances for the Robins since signing on-loan from Wolves in March and scored in the first leg of the semi-final clash with Sheffield United at Bramall Lane, experienced Wembley glory with Hull in the Championship play-off final of 2008.
As a result, he knows what it takes to succeed at the national stadium and he’s offered some words of wisdom to the rest of the Swindon squad prior to Sunday’s meeting with the Lilywhites.
“You need to be mentally ready, you need to be tactically ready, you need to be ready for eventualities,” he said. “You need to be ready if you’re winning with 10 minutes to go, if you’re losing with 10 minutes to go, if they play one formation – you need to have all the answers.
“There’s no ‘we can put it right on Tuesday, lads’. This is the game now where everything matters and that’s what brings great excitement.
“When we get there on Sunday it will be all about the football. It’s a hugely talented team and hopefully we can produce the performance we know we can do and get the result we want.”
Meanwhile, the 33-year-old – by far the oldest member of the Swindon side – believes the size of the Wembley pitch could well suit the Robins’ passing game.
“It certainly helps us, the more room we’ve got to pass the ball. We’ll pass the ball on a tight pitch,” he said.
“Pitches make a difference but we’re only talking about five metres or so. If we can perform to the level we know we can then we know we’re in with a great chance of winning the game.”
