Advocaat's side have not won in the league this season

Sunderland manager Dick Advocaat says he has no regrets about remaining in the job but will leave the post if he feels there is somebody better for it.

Advocaat was set to depart after keeping the club in the Premier League last season but was persuaded to stay and signed a one-year deal.

But his side are bottom, and winless, with two points from six games.

"Let's be clear, if I feel it is better for somebody else to take over then I will go. Believe me," said Advocaat.

Advocaat joined the club in March until the end of the season, replacing the sacked Gus Poyet, with the side one point above the relegation zone.

The 67-year-old former Rangers and Netherlands manager was offered a new deal at the end of the 2014-15 season, but had told the club "it is better to stop now", before being persuaded to change his mind.

Sunderland were beaten 2-0 at Bournemouth on Saturday and next host Manchester City in the League Cup on Tuesday before a league trip to Manchester United on Saturday.

Black Cats centre-back John O'Shea is expected to be back in the side against City after recovering from illness but fellow defender Younes Kaboul is suspended following his red card on the south coast.
