ROB Kiernan cannot wait to get started at Southend United.

The centre-back - who had a loan spell with the Shrimpers in 2013 - has rejoined from Rangers on a three-year contract.

And the 26-year-old has already set his sights on a successful season at Roots Hall.

“I wanted to join a club who have ambitions to achieve something this year so I’m delighted to have joined Southend,” said Kiernan.

“I already know the manager from being here before and he was a big part in me wanting to come back to the club.

“I did enjoy my time at Rangers but I’m happy to be back down south and I can’t wait to get started now.”

Kiernan, who will wear the number 15 shirt, trained with his new team-mates yesterday.

But the defender admits he is at least a week away from full fitness after enduring a disjointed pre-season.

“It’s no secret that the training session I had yesterday was actually my first of pre-season,” said Kiernan.

“It was great to get my boots back on and get out there again and I’m not actually that far off it.

“I’ve worked hard on my own during the summer.

“I’ve done plenty of running, cycling and general fitness work to keep myself in good shape.

“Obviously playing matches is completely different but hopefully in a week I’ll be fully fit and really ready to make a difference.

“But it’s up to the manager when I’ll be involved.”

Kiernan’s arrival will boost a Blues squad short of defensive options following injuries to Michael Turner and Ben Coker.

However, Kiernan was forced to remain patient during prolonged talks between the two clubs.

“It did take a little while to get done but there were a few bits and bobs to get sorted out and that happens in football,” said Kiernan, who made 15 appearances during his previous spell with Southend.

“Some days I thought the move was going to happen but then I would get a call to say it wasn’t happening.

“But the main thing is it’s all been sorted now and I can really focus on my football and making sure I play regularly.”

And Kiernan believes it will not take long for him to settle with Blues.

“A few of the boys are still here from when I was here last time and it’s always good to see some familiar faces at a new club,” said the defender.

“I’m excited to be back.”
