Following an injury to Michael Nelson that left Norwich short of defensive cover at centre-back, Paul Lambert signed Leon Barnett on loan from West Bromwich Albion on 26th August 2010 until 4th January 2010.

Barnett, 25, joined the Baggies from Luton Town in July 2007 for an initial fee of £2.5million and has since made 55 league and cup appearances for the Midlands side, netting three goals in the process. He had made a total of 78 appearances for the Hatters, and scored three goals. He had progressed from Luton's youth academy and had a loan spell as a youth with Aylesbury.

The 6ft 1in centre-back joined Coventry City on loan lin 2009/10 and made 20 appearances for the Sky Blues.

Lambert said "He's a quality player who has played Premier League football as well as having solid experience at Championship level, so I'm delighted we've been able to bring him in. "He's here until January so he will provide competition for places when Michael and Zak Whitbread are fit again, which I think you've got to have."

Barnett made his debut on 28th Augist 2010 in the 1-1 draw at Notts Forest

Impressing for Norwich, it was announced on 10th December 2010 that Norwich were to make Leon's stay at Carrow Road permanent in the January transfer-window having agreed a price with West Brom. However the following day, he conceded a penalty against Portsmouth and was then sent off, receiving a n additional two match ban for throwing the ball at the referee.

Leon signed permanently for Norwich in January 2011 but his season was cut short soon afterwards by injury. He ended the season with 26 appearances and 1 goal
