Swiss international defender Bruno Berner joined Norwich City on trial in the first few days of July 2008

Berner was released by Blackburn Rovers at the end of 2007/8, having failed to make the jump from the Swiss League to the Premier League. He had played for Grasshoppers Zurich, German side Freiburg and FC Basel before moving to Ewood Park for a trial in January, 2007. He signed an initial 18-month deal, with the option of a further year, and made two appearances before the end of the 2006/7 season.

He made just four more appearances in league and cup in 2007/8 and soRovers decided not to take up the option of a further year, releasing him, along with fellow Swiss Stephane Henchoz and goalkeeper Peter Enckelman.

He is experienced at international level with 16 caps, although he was an unused member of the Swiss Euro 2004 squad in Portugal. He can play at left-back, central defence, wide left and left midfield.

Since leaving Norwich after his short trial, he had been in negotiations with Leicester and Notts Forest but suprisingly was linked with West Ham on 7th August 2008 who are in need of cover at left back as first choice George McCartney is out with a hamstring injury. On September 12th 2008, Berner joined Leicester City on a three-year contract and was handed the number 31 shirt. He made his debut in a Johnstone's Paint Trophy match against Lincoln City at the Walkers Stadium on 23 September, drawing 0-0 but winning 3-1 on penalties. He scored his first goal for Leicester in a 2-1 away win over Carlisle on 13 December 2008, his first in three years. Leicester went on to win the League One title

Berner retired in March 2012 having played only eight games since signing a one year contract in January 2011.

On 20th June 2012, it was reported that Berner had been appointed coach of FC Zurich's Under-15s

In November 2016, Bruno was appointed manager of Swiss third division side FC Tuggen who were bottom of the league. In June 2017 he left Tuggen to become manager of SC Kriens. In the 2021/22 he coached the Under-19 and Under-20 national teams before being confirmed as head coach of FC WInterthur.

On 9 June 2023 he was appointed head coach of his childhood club Grasshoppers Zurich on a two year contract.
