Manager Paul Sturrock felt his side was worthy of a point against Burton Albion on Tuesday night.
Blues suffered a 1-0 defeat against the Brewers at Roots Hall despite playing 79 minutes with 10 men following John Spicer’s red card.
However, an injury time strike from Albion’s Jacques Maghoma left Southend empty handed.
“It is a cruel game football,” Sturrock told the official website.
“We looked a very competent side with ten men and the players rolled their sleeves up and gave everything they had.
“It was a huge kick in the teeth at the end of the game and everyone’s heads are down at the moment, as they didn’t deserve that in the end.
“We definitely should have had something from the match.
“I would have liked to have seen 11 versus 11 as the way we played with ten men I could only see one winner.”
Southend’s task was made harder when referee Keith Stroud sent off John Spicer in the eleventh minute for a two-footed tackle on former player Matt Paterson.
Spicer was shown a straight red card and will now face a three-match ban.
“He had his back to me so I couldn’t see how high he raised his legs but you can’t make tackles like that in the modern game now,” said Sturrock.
“He should have stayed up on his feet.”
Spicer’s ban adds to Blues selection woes with Barry Corr midway through his own three game suspension.
Mark Phillips, Gavin Tomlin and Neil Harris are also out with injuries whilst Ryan Leonard added to that list after he pulled up ahead of Tuesday’s match.
“Ryan Leonard pulled a hamstring in the warm-up,” confirmed the Scot. “He would have definitely played a part tonight with his long throws and we could have done with his general play in midfield.
“I am very hopeful that some of the injured players we have at the moment will be able to play a part on Saturday.”
Sturrock also explained that a lack of training after a neck injury meant he went with 19-year-old keeper Daniel Bentley once more despite Paul Smith’s inclusion amongst the substitutes.
“Smith hasn’t had any training days at all with the concussion,” he said.
“He did one session on Monday but I felt he needed to build himself back up again.
“Paul will be our number one goalie even though Daniel has done a fantastic job.
“He is a competent goalkeeper and it is nice to know now that we have competition for that place.
“Although he was a novice at the beginning of the season he has all of a sudden matured and shown an inner strength I didn’t think he had.”
