Milan Mandarić (Serbian Cyrillic: Милан Мандарић; born 5 September 1938) is a Serbian-American businessman who has owned a string of businesses and association football clubs, including Portsmouth, Leicester City and Sheffield Wednesday.

The firm was successful, but disagreements over manufacturing processes led to Mandarić leaving to form his own company, Lika Corporation, in 1971.

In 1976, he became a naturalized citizen of the U.S. By 1976, Lika Corp. was the largest manufacturer of computer components in the U.S., and Mandarić was pioneering the boom that led to the creation of California's Silicon Valley.

[2] Around the same time he had begun using his money to invest in football, Mandarić's passion since childhood (as a young man he had played for Novi Sad).

In 1978, he purchased a North American Soccer League franchise called the Connecticut Bicentennials and moved them to Oakland, California, to play as the Stompers.

[6] After the club's survival that season, Mandarić sold his remaining share of Portsmouth to Gaydamak, but stayed on as a figurehead in his role as non-executive chairman.

On 24 February, Mandarić made a bid for East Midlands club Leicester City, believed to be in the region of £25 million.

[7] Despite setting an initial takeover deadline of 15 December, negotiations stalled, reportedly after hidden debts in the club's accounts surfaced during the due diligence period.

Indeed, on 2 January the Leicester Mercury reported that the deal was in fact close to completion after Mandarić's revised terms were accepted by the club's board.

[9] On 25 January, Mandarić put his bid for Leicester on temporary hold after news of his mother's illness back in Serbia.

There were wild rumours that suggested he was on the verge of pulling out and, indeed, the delay guaranteed that manager Rob Kelly would not enjoy the benefit of a cash injection before the season's transfer window closed on 31 January.

[11] Mandarić was arrested on 28 November 2007 over allegations of corruption in football, along with Harry Redknapp, Peter Storrie, Willie McKay and Amdy Faye.

After tumultuous times, however, things started to look up for Mandarić as Leicester were crowned champions of League One on 18 April 2009 under the stewardship of Nigel Pearson.
