ATHENS, June 11 (Reuters) - Greek champions Olympiakos Piraeus have sacked Portuguese coach Vitor Pereira after six months in charge at the club, during which time he led them to a Greek league and cup double.
Local media said the 46-year-old had angered Olympiakos owner Vangelis Marinakis when it was reported he held talks with Scottish club Rangers last month.
"Olympiakos announces the termination of its cooperation with the coach Vitoria Pereira by mutual consent," said a brief statement on the club's website.
Pereira made his name at Porto, where he won two consecutive Portuguese league titles, and penned a two-and-a-half-year contract with Olympiakos in January.
