Fleetwood boss Graham Alexander is desperate for his side to get through 90 minutes this weekend without conceding a penalty.
Town have given away spot-kicks in their last two matches, conceding from neither.
Ian Henderson rattled the woodwork at Rochdale, where Fleetwood ran out 2-0 winners.
And Chris Maxwell was the hero last Saturday, diving to his right to save Andy Williams’ poorly-placed effort following a foul on Swindon’s John Swift.
It was the sixth penalty Town have conceded this season – the joint-highest total in League One.
Alexander admits his side have given away too many penalties this season – a record which began in the opening day victory over Crewe Alexandra.
Spot-kicks have previously proved costly for Town, deciding the outcome of games at Oldham and Milton Keynes.
And Alexander wants to give nothing away for free as Fleetwood head to the capital to face Leyton Orient.
He said: “It’s been the story of our season, right from day one. We conceded one on the first day.
“We’re a little bit guilty of diving in inside the box and we put ourselves at risk.”
The Fleetwood manager will impress on his players the importance of standing their ground in the box and not making it easy for opponents – as Jeff Hughes did with his lunge on Swift at the weekend.
But Alexander still feels aggrieved by many of the decisions which have gone against his side.
He said: “I’d say 60 per cent of those penalties against us shouldn’t have been given. The one against Rochdale wasn’t a penalty.
“It seems to be a little bit of an easy thing against us. It’s not a big deal if they give them. Saying that, at the time I thought it could have been a penalty.”
n Town are yet to reach a deal with Blackburn Rovers over the return of Josh Morris for the trip to Leyton Orient.
Morris, who first joined Town on loan last February, played the last game of his latest spell at the club last Saturday, scoring both goals in the 2-2 draw with the Robins.
Alexander wants to keep hold of the left-sided midfielder, who is keen to stay but Rovers are understood to want more favourable terms for the loan deal.
Morris signed a new contract at Ewood Park in the summer and the club have since been hit with a transfer embargo for breaching financial fair play rules.
One man certainly not Highbury-bound is Blackpool’s Bobby Grant.
The striker was this week linked with a cash transfer to Town but has returned to Micky Mellon’s Shrewsbury to continue his loan spell until the end of the season.
