Andy O'Brien (footballer)

He was transfer listed by Neil Warnock at the end of the 2011–12 season and told to find a new club. On 4 May 2012, O'Brien lost his squad number, when the number 5 shirt previously occupied by him was given to new signing Jason Pearce.

On 1 August 2012, O'Brien moved to Canadian MLS club Vancouver Whitecaps FC on a free transfer from Leeds United. Having signed a two-year contract, he made his debut on 8 August against Real Salt Lake. In his second MLS season, having already made 25 appearances in his first year of service, it was announced that he had signed a one-year extension with the Whitecaps. After the conclusion of the 2014 campaign, O'Brien entered into contract talks with the Whitecaps, but the two sides were unable to reach an agreement. After 50 appearances for the club, it was announced that Whitecaps were "moving in a different direction," and thanked O'Brien publicly on Twitter.

On 1 January 2011, O'Brien signed a permanent deal with Leeds United on a .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}2+1⁄2-year contract, which took effect after his loan deal came to an end on 4 January 2011. He turned down a lucrative offer from Cardiff City, opting to move permanently to Leeds. On 8 January, O'Brien put in an impressive performance to help earn Leeds a 1–1 draw against Arsenal, Leeds were 1–0 up when Robert Snodgrass scored a second half penalty, Arsenal equalised in the 90th minute when Cesc Fàbregas scored a penalty. O'Brien picked up an injury in the FA Cup replay against Arsenal and subsequently missed the game against his former club Portsmouth. O'Brien scored his second goal for Leeds in the 3–2 loss against Millwall.

After picking up a hip injury during the 2011–12 pre-season he missed all the pre-season games, to return against his former club Newcastle United. Then stepped up his recovery against Leicester City in a behind closed doors friendly. The summer also saw O'Brien take the number 5 shirt after previously occupying the number 40 shirt. O'Brien started for Leeds the opening day of the season as they crashed to a 3–1 defeat against Southampton, with O'Brien at fault for the second goal when his backwards header was converted by Adam Lallana. He was given a torrid time against his former club Bradford City and was substituted to loud jeers in the second half with Leeds 2–1 down. Leeds went on to win the game 3–2. O'Brien dropped out of the Leeds squad for the following game on 13 August against Middlesbrough in a match Leeds lost 1–0.

During the 2010–11 season, O'Brien picked up a hamstring injury for Bolton in the Premier League game against Aston Villa. O'Brien joined Leeds United on an initial one month's loan on 29 October 2010. Manager Simon Grayson said of the move "Andy has had a fantastic career, and has great experience. He's a leader and will be a valuable member of the squad for the next [month]." The move saw O'Brien re-join the club he started his career at, he was released by Leeds 17 years earlier as a 14-year-old. O'Brien was given squad number 40 and made his debut for against Scunthorpe United. In November 2010, O'Brien revealed that he would be interested in possibly making his loan move to Leeds permanent. O'Brien scored his first goal for Leeds with a header against Hull City. On 24 November, the loan was extended until 4 January 2011.

On 11 April 2009, O'Brien scored his first goal in four and a half years, and his first goal for Bolton, against Chelsea at Stamford Bridge. After being a regular starter under Gary Megson, O'Brien found himself on the substitutes bench when Owen Coyle took over, with Gary Cahill and Zat Knight the preferred central defender partnership. After Middlesbrough offered to loan O'Brien from Bolton, Owen Coyle rejected the loan move preferring to keep O'Brien as backup

In May 2008, his efforts were recognised by Wanderers supporters when he was named as The Bolton News Player of the Season following a poll held by the newspaper.

On 7 October 2008, O'Brien signed an extension to his contract at Bolton until 2011 and once again reaffirmed his happiness at the Reebok Stadium.

After being picked for the squad to face Brazil on 6 February 2008, he did not report for training on 3 February 2008 and Ireland caretaker manager Don Givens received a message from O'Brien announcing his retirement from international football. He played 26 games for Ireland, with his last coming against Cyprus on 7 October 2006.

There were rumours that Sunderland's Irish boss Roy Keane would sign the centre back. This came after Keane signed many Irish players to represent Sunderland. Instead he signed for Bolton on 13 August 2007.

O'Brien has dual British-Irish citizenship, and despite representing England at under 18 and under 21 level, he elected to represent the Republic of Ireland at under 21 and senior level. O'Brien's performances for Newcastle led to him being called up to the Republic of Ireland national football team, earning his first cap against Estonia in Tallinn in 2001. He later became a regular in the Irish squad, and was included as part of their 2002 World Cup squad. He scored his first, and ultimately only, goal for Ireland to give his country a 1–0 win against Portugal on 9 February 2005.

Despite several years as a solid defender at Newcastle, O'Brien suffered from poor form in the latter part of the 2004–05 campaign, as Newcastle finished a disappointing 14th in the Premier League. However, his reputation was such that Portsmouth paid £2 million to bring him to Fratton Park.

He was a regular in the Bradford City side during its two years in the Premier League, forming a partnership with club captain David Wetherall in central defence. In 2000–01, City were in financial difficulties and facing relegation when Newcastle United bid for O'Brien. After 133 league appearances he moved to St James' Park in March 2001 for a club record £2 million fee, equalling the same fee Des Hamilton had also left Bradford City to Newcastle.

Born in Harrogate, England, O'Brien began his footballing career at St John Fisher Catholic High School, Harrogate, under the stewardship of his manager, Max Mills. He joined Leeds United's academy and played in the same youth side as Harry Kewell and Jonathan Woodgate, however O'Brien was released by Leeds at the age of 14. His talent as a defender was spotted by Bradford City and joined their junior ranks in 1994. He made his senior debut in October 1996 against Queens Park Rangers. He soon became a regular in the Bradford City first team, and helped the Bantams to promotion to the FA Premier League during the 1998–99 season.
