Tottenham Hotspur

Thanks to his prodigious goal scoring rate at reserve level, he was expected to make his first team debut in the 2005–06 season. He was due to make his debut in the match against Charlton Athletic on 5 February 2006. Tottenham were leading 3–0 until a Charlton goal in the 69th minute meant Martin Jol did not want to bring on another striker so Barnard had to wait. Following the match he suffered a foot sprain which kept him out of action for five weeks, only returning for the reserve match against Leicester City on 18 March.^{[citation needed]}

On 17 April, he finally got to make his Premier League debut in the 2–1 defeat to Manchester United at White Hart Lane, coming on after 77 minutes as a substitute.^[4] He also came on the following week against Bolton Wanderers.^[5]

Barnard was one of ten Spurs squad members to be struck down by a virus on the evening of 6 May before their crucial final game of the season against West Ham United. Unable to postpone, they went on to lose and therefore slipped to fifth.^[6][7] This allowed rivals Arsenal to take the fourth Champions League place for that season.

On 30 August 2007, Barnard was loaned out to League One team Crewe Alexandra for five months, after a delay due to an injury in training.^[8] Barnard made a scoring début in the Railwaymen's 2–0 home win over Huddersfield Town on 8 September 2007. However, he damaged ankle ligaments in late October and returned to Spurs for two months for treatment.^[9][10]

Southend United

On 29 January, Barnard made his full league debut against Leeds United and scored the only goal of the game in the 41st minute, pouncing on a loose ball after Steven Hammell's free kick had hit the post. Barnard scored nine goals from January until the end of the season, including an injury time winner at Carlisle United, who had the best home record in the league. Barnard endured a frustrating 2008–09 season due to injuries, despite this he still finished the season as the club's top scorer and the only player in the squad that season to reach double figures, getting his 10th goal of the campaign away at Northampton Town.^{[citation needed]} Southend had only lost once when Barnard has scored.^{[citation needed]} He started the 2009–10 season scoring four goals in his first three matches, and scored his first professional hat-trick in the 3–0, League One victory over Leyton Orient on 4 September.^[12] On 30 October, Barnard scored a 93rd-minute winner against Gillingham, he followed that up with another last minute goal, this time from the penalty spot against Milton Keynes Dons in the 2–1 win. On 12 December 2009, Southend came from 2–0 down to beat Hartlepool United 3–2 with Barnard scoring a brace. His last goal for Southend came on 28 December at Leyton Orient, with Southend claiming a 2–1 victory. He made his last appearance for Southend away to Huddersfield Town in the 2–1 defeat. In his two years at the club, Barnard made 85 appearances for Southend and scored 37 times.

Barnard signed for Southampton on 22 January 2010 for an undisclosed fee, with Matt Paterson joining Southend. He had scored 17 goals in all competitions for Southend in the 2009–10 season.^[13] He made his debut the following day against Ipswich Town in the FA Cup in a 2–1 win. He made his league debut for the club on 26 January, against Brentford in a 1–1 draw. On 20 February, Barnard scored his debut league goals for Southampton, against title challengers Norwich City, scoring both goals in the 2–0 win which saw the end of Norwich's 11-match winning run. A week later he showed the same form as he netted a brace against Walsall in a 5–1 victory, and then scoring again three days later in the 5–0 win over Huddersfield Town. In the 2010–11 season he scored twice against Yeovil in a 3–0 victory and four days later scored the first goal in a 3–1 away win at AFC Bournemouth.
