There are growing concerns inside Manchester City that Sven Goran Eriksson may quit before the end of the season.

The Daily Mail says after another round of criticism by City chairman Thaksin Shinawatra yesterday, Eriksson may choose to jump before he is pushed.

Just weeks after Thaksin said he was paying a visit to his club to "tighten the bolts", the 58-year-old went several steps further yesterday by hitting out in a way that has concerned executives at City.

So far, Eriksson has not raised the possibility of quitting with anybody at the Barclays Premier League club. Both publicly and privately the 60-year-old has stressed that he sees his work at City as a long-term project.
