John Sheridan has stepped down as manager of Swindon Town with the team on the brink of relegation from League One.
Beaten 4-1 by AFC Wimbledon yesterday, Swindon are seven points away from safety with just four games remaining.
Sheridan, a former Republic of Ireland player, had been in charge of Waterford FC last year for a short spell before returning to England to manage Wigan.
The 56-year-old took charge of Swindon in November and his contract was due to expire this summer.
"It's a difficult decision for me to make but they've still got a little chance of staying in this league," he told the BBC.
"There are four games to go and hopefully someone can come in and work a miracle and pick the team up and try to get a few results.
"It's time someone else gets an opportunity and hopefully they can turn it around."
