Manager Paul Sturrock is eager to extend his sides’ unbeaten run against Gillingham on Tuesday night.
Blues travel to the Kent sides Priestfield Stadium unbeaten in their last five matches.
But as they prepare to face the League Two table toppers, Sturrock knows they will have to be on top of their game to extend that run to six.
“Gillingham have made a great start to the season,” Sturrock told the official website.
“Martin Allen has obviously got them ticking as they haven’t lost in the League yet.
“Danny Kedwell is the divisions top scorer also so we will have to keep an eye on him but they have threats all across the park.
“That means we are in for a tough test but we are in good form also and so we should be confident.
“We’re unbeaten in our last five and it’s important that we try to make that six.”
Saturday’s 3-1 win against Cheltenham Town saw Southend United move up to 8th in npower League Two.
However, injuries continue to trouble Sturrock’s squad with Neil Harris missing the trip to Whaddon Road with a knee problem.
He joins Freddy Eastwood (calf), Luke Prosser (calf) and Ryan Leonard (hamstring) in the treatment room.
But despite that Sturrock is confident his side can go to Gillingham and get the required result.
“We are starting to climb the league now,” he said.
“I am very pleased for everybody associated with the club as we have all worked very hard.
“We’ve had some niggling injuries which have made things hard but everyone has worked tirelessly.
“We can go and enjoy ourselves tomorrow night and try and peak again like we did against Cheltenham.”
