Harry Wheeler has demanded concentration from Maidstone in the FA Cup this weekend.

The Stones host Leyton Orient on Saturday looking to reach the first round for the fifth year running.

To do so, they'll need to avoid a repeat of the opening goal that cost them at AFC Fylde in the National League.

Maidstone were playing well against the Coasters last Saturday but switched off at a corner and lost 2-0.

Boss Wheeler said: "It shouldn't be difficult to concentrate. We train regularly enough.

"I'm asking you to concentrate for an hour and 35 minutes out of 24 hours in your whole day, so it's not asking for a lot percentage-wise.

"It's not a mistake, it's a concentration thing.

"Everyone makes mistakes, and that's fine, but when it's down to concentration, that's the disappointing thing for me."

Maidstone face a difficult task against an Orient side who sit second in the National League.

Wheeler has upped training to four days this week in preparation for the high-flying Londoners.

He said: "We're in Tuesday, Wednesday, Thursday, Friday, so we're going to work hard and do everything we can to get a positive result and go through.

"I fully believe we've got a great chance if we get ourselves right.

"It's an important cup for us and we'll give it everything we've got.

"I've always had a good record in the cups and hopefully we bring that here and continue that because Maidstone have had a good record too.”

Midfielder Jack Powell is set to make his home debut after joining from Ebbsfleet.

Wheeler is thrilled to have him.

He said: "I spoke to my friend on Monday who's been managing in the Football League for three years and he couldn't believe we'd signed him.

"He said he went to watch him last week or the week before and that he's really highly rated.

“It's a great signing for us, it's massive for us, but it shows what we're building."

Wheeler also understands why captain Stuart Lewis chose to leave for Dover.

He said: "I don't blame Stuart, he's a lovely guy and a great professional.

"He's done really well and he's been offered better money.

"He's got a child on the way, he's been offered more security, so for his family, which is the most important thing in life, he's decided to move and we wouldn't stop him.

"Football's not personal, it's business.

"I don't take anything personally and neither should anyone the other way.

"He's done what's right for his family and we wish him all the best."
