Aston Villa captain Stiliyan Petrov has heaped praise on manager Martin O'Neill.
Petrov followed O'Neill from Celtic to Villa Park.
"This is Villa's first final in 10 years and I have been here for the last four years," he told the Scottish Sun. "It is a great club and the fans are brilliant, I want to repay them.
"It will mean a lot to Martin to win on Sunday.
"He won so much in Scotland, but still people questioned him. They asked: 'Can he do it again in England'? He had already been successful with Leicester City, winning the League Cup a couple of times.
"He's doing a great job for Villa and it would mean so much to him to pick up silverware for the club."
