Midfielder Josh Cullen feels both the Charlton players and fans are ready for the special atmosphere of Sunday’s League One play-off final with Sunderland (Charlton 2/1, Sunderland 13/8, draw 11/5 – Match Betting).

The Addicks booked their spot in the Wembley showpiece with a penalty shootout victory over Doncaster Rovers after the tie ended up 4-4 on aggregate.

The Black Cats and Portsmouth could only score one goal between them in their two-legged last-four clash but it was the Wearsiders’ Chris Maguire who bagged it at the Stadium of Light to give the north-east outfit a shot at returning to the Championship.

Sunderland took four points from the clubs’ regular-season meetings this term but, as ever in the play-offs, the form book will be ripped up in north London.

It is a huge occasion for anyone connected with the south Londoners and, having been out of the Premier League since 2006, they will be desperate to take the first steps back with a return to the second tier of English football.

Support will be key and Cullen, on-loan from West Ham, reserved praise for the way The Valley faithful continue to back their heroes.

“Playing in front of a big crowd is obviously different and I should mention our fans have been fantastic and they’ve stuck by us and going to Wembley is for them,” he said. ” I’m sure they’ll pack it out again.”

Charlton are the underdogs to be promoted, even though they finished three points ahead of Sunderland after 46 games (Sunderland 5/6, Charlton 10/11 – To Be Promoted).

And, with that in mind, Cullen insists that preparation has been spot on with no stone left unturned in the quest to get things right.

“The lads are buzzing to be playing at one of the best stadiums in the world and will be ready,” he added. “We will all prepare right and be mentally and physically ready to go on Sunday.”

Odds subject to change.
