John Sheridan’s side lost their opening leg of the League Two play-off semi-final at Home Park. However, two goals in the final six minutes of last Saturday’s match courtesy of Zak Ansah and Jason Banton have given the Pilgrims hope that they can reach the final on May 23.
Away goals do not count as double in the play-offs so Argyle just need to win by one goal at Adams Park to progress.
Argyle manager Sheridan feels the first goal on Thursday could decide the tie.
“I think it’s about the next goal,” said Sheridan. “Wycombe are at home and if they come at us and get a goal it would give them a big lift and obviously a big boost.
“Obviously they’re the favourites, they’ve got the advantage of the goal, but I think the players are really confident they can get the result we’re after.”
Argyle will be boosted by 2,000 away fans at Wycombe. The players credited the Green Army for helping them get back into the tie at Home Park.
