Manager Paul Sturrock believes Southend will be "caught out quite soon" if they do not make an impression at the start of games, despite seeing his side claim a 4-1 win over Torquay.
All four of Southend's goals came after the interval, with Kane Ferdinand bagging a brace before Liam Dickinson and Mark Phillips sealed the rout.
"I was pleased with how we played in the second half but we need to really be playing like that right from the start of matches," said Sturrock. "If we don't start to do that then we're going to get caught out quite soon because you can't just keep turning it on and off whenever you want."
He added: "We have to make sure we play at a high tempo from the off but thankfully it didn't cost us against Torquay and we were still able to get the three points."
Ferdinand played a huge part in that happening as he grabbed Southend's first two goals from midfield.
And Sturrock feels Ferdinand, who is the cousin of Manchester United and England star Rio, is capable of hitting the back of the net more regularly.
"I've changed Kane's role in the team because he's a natural finisher and he showed that out there," said Sturrock. "He has that ability and that's why I've been encouraging him to get into the box more."
In contrast, Torquay boss Martin Ling praised his side's first-half performance but was left to rue a lack of concentration after they conceded four goals in 25 minutes.
"We were quite solid in the first half but conceding so early in the second half was disappointing and we made it too easy for Southend after that," said Ling.
"To concede four times like we did in the space of 25 minutes is poor and we're frustrated by that. Southend don't need any encouragement at the moment because they're full of confidence. However, we're lacking that after going eight games without a win and need to keep on working hard to turn it around."
