Derry City have signed Republic of Ireland under-23 defender Ger O'Brien on a three-year contract from Shamrock Rovers.
O'Brien can play at full-back or centre back and said the presence of Stephen Kenny as manager convinced him to make the move.
"Everyone knows that Stephen Kenny is such a good manager. He's brought success here and to most places he's been," he said.
"Hopefully I can come in now and add to that and we can have more success."
"Ger can play left or right back, while last season whenever they came to the Brandywell he actually played centre-back," said Kenny (pictured).
"He's a player with a good engine who likes getting forward, so he's a very good attacking full-back.
“Rovers have so many players, I think around 24 players, and I think their new manager wants to bring in some players from Scotland, so it was an opportunity for us to get Ger.
"We only have five defenders at the club and Clive Delaney is suspended for the opening few games of the season, so we needed to get another defender. Ger's versatility will be important.
"He has a good attitude and good mentally, but he still has a lot to prove and more importantly he's hungry but I think he'll be a good addition for us."
Derry City will kick-off the 2009 season with a game against Drogheda United at Brandywell on March 6. The season will end with a game at Dundalk on November 6.
Champions Bohemians open their defence with a trip to Oriel Park to face newly promoted Dundalk.
Meanwhile Dungannon Swifts are to sue Derry over money they say they are owed over Niall McGinn’s transfer from Brandywell to Celtic in December last year.
According to the Swifts they will take legal action to force Derry to inform them of the transfer fee that the Candystripes got for McGinn.
The Swifts say they are entitled to 20% of the cash that Derry received from Celtic for the Northern Ireland player.
Dungannon chairman Jarlath Faloon says that Derry have so far refused to divulge the fee or pay them anything from the move.
"We have issued a writ today to the High Court in Belfast," said Faloon.
"We have also reported Derry to the Irish FA and Football Association of Ireland.
"We have written to Derry City and told them repeatedly since December and we haven't received any answers to our phone calls or any replies whatsoever to numerous correspondence.”
