LISBON, May 7 (Reuters) - Portugal coach Luiz Felipe Scolari, reportedly the target of English Premier League side Manchester City, is unlikely to decide on his future before Euro 2008, a source close to the Brazilian said. British media reported on Wednesday that Manchester City have made an offer to Scolari and that the deadline for him to accept is before the start of the Euro 2008 finals next month. 'It is very unlikely that Scolari makes any decision now, one month ahead of the championship,' the source said on Wednesday. The Portuguese Federation would not comment. Scolari, who joined Portugal in 2003, has told the Portuguese media he would only discuss his future after Euro 2008. Speculation surrounds the future of Manchester City coach Sven-Goran Eriksson with British media reporting the former England coach would resign or be sacked after City's Thai owner Thaksin Shinawatra said he was unhappy with the club's form and wanted change. Last week, Eriksson's agent said the Swede would unlikely still be Manchester City manager next season.
