A look over the Blues' January transfer dealingsAs the transfer window has now shut, we take a look at the incomings and outgoings at Roots Hall.
Tyrone Barnett has firmly hit the ground running for the Blues since joining from Shrewsbury Town on loan until the end of the season.
The target man, who collected a brace in the last home fixture, brings a proven track record of goals to the table.
Whilst a player at Crawley Town, Barnett bagged an impressive 15 goals in 33 games, which is just over a goal every other game. That form earned him a move to Peterborough, in a deal in excess of £1million.
Barnett, who has already shown Southend fans a glimpse of what he can do with three goals in as many games, will be hoping to achieve further success at Roots Hall.
Like Barnett, Stephen Hendrie was another player who went straight in to the thick of the action after signing for the Blues.
The full-back, signed on a one-month loan deal from West Ham United was brought straight in to the starting 11 for the game against Peterborough, replacing the injured Ben Coker.
Hendrie proved a pivotal figure of the back-line that day, helping the side earn a battling 0-0 draw against one of the league’s top-scoring sides.
Taking to the role of wing-back like a fish to water, Hendrie was involved in the build-up to two of the three goals scored in his home debut against Coventry City.
The player is a Scotland U21 international, and joined the Hammers last summer, after progressing through the youth system at Hamilton Academicals.
Attacking midfielder Sam McQueen joined the Blues on loan from Premier League side, Southampton.
The midfielder, 20, is a product of the famed Southampton academy, and has been at the club since the age of eight.
The attacking midfielder progressed through the ranks to make his Saints debut in February 2014; coming on as a substitute in a fifth-round FA Cup tie against Sunderland.
The player made his debut as substitute in the Coventry triumph, and will look to gain some vital first team experience in his time at the club.
Defensive midfielder, Glen Kamara was signed from Arsenal until the end of the current campaign.
The defensive midfielder, 20, was on the Blues books in 2012, before making the switch to the Gunners. Kamara was only at Southend for one season, arriving from his native country of Finland.
Despite his young age, Kamara already has first team experience at club and international level.
Phil Brown will be hoping that the player can apply that experience to the Blues between now and the end of the season.
The club announced the loan signing of Jamar Loza from Norwich City, until the end of the season last week, with a view to a permanent deal in the summer.
The striker made seven appearances for the Blues in a previous spell at the club in 2014, and spent a period on trial at the club this January.
Loza has been capped four times for the Jamaican National Team and has scored once in six appearances since coming through the youth ranks at Carrow Road.
Southend United defender, Luke Prosser joined League Two side Northampton Town last week.
The defender joins the Cobblers on loan until the end of the season when his current contract at Southend United expires.
The defender has made 16 appearances for the Blues this season, scoring two goals.
Prosser has been at Roots Hall since 2010, making over 100 league appearances for the club.
Prosser could be in line to make his debut for Chris Wilder’s side in the Cobblers next fixture against York City this weekend.
