Both the Hoops manager and backroom staff have been full of praise for the Hoops faithful throughout the season and he's asking them to bring the noise ahead of Wednesday's crunch tie.
"We say it every week, the fans are brilliant," said Jenkins. "They don't have to travel but they do, they spend a lot of money travelling and they bring the atmosphere.
"We appreciate all the fans and the players do too. We've got a big game on Wednesday so it's important we do the business on the pitch to keep the atmosphere loud and get the place buzzing."
Tickets are selling quickly for Wednesday's Vanarama National League South Eliminator tie against Eastbourne Borough (K.O 7:45PM) and Jenkins has said that it will make for a great atmosphere.
“As a fan it's a brilliant game for a neutral to come and watch. If we weren't in the play-offs I'd probably go and watch a play off game myself.
"There's high emotions, the atmosphere should be good but when you're in it you can get carried away with it all so we've got to make sure we have the right balance.
"But as I said for the neutral it should be a good game, obviously there's a lot riding on it so emotions will be high so hopefully we can put a good performance in for the fans because they're been brilliant."
