Scott Parker has been sacked by newly-promoted Bournemouth after their drubbing by Liverpool over the weekend.
The 41-year-old’s departure comes three days after Saturday’s 9-0 thrashing at Liverpool.
Cherries co-owner Maxim Demin said: “I would like to place on record my gratitude to Scott and his team for their efforts during their time with us.
“Our promotion back to the Premier League last season under his tenure will always be remembered as one of the most successful seasons in our history.
“However, in order for us to keep progressing as a team and a club as a whole, it is unconditional that we are aligned in our strategy to run the club sustainably.
“We must also show belief in and respect for one another. That is the approach that has brought this club so much success in recent history, and one that we will not veer from now. Our search for a new head coach will begin immediately.”
Gary O’Neil will take interim charge of the first team, assisted by Shaun Cooper and Tommy Elphick.
Asked in the wake of defeat against Liverpool if he hoped that the 9-0 defeat was the lowest point of Bournemouth’s season, Parker said: “At this present moment in time, yeah for sure. Definitely.
“But at this moment in time, where we currently are, I can see some more, to be honest with you.
“We need to make a decision. That’s just where it is. I think I’ve been clear on that from the minute I stepped in.
“I’ve been clear throughout all of that in terms of how this season could look for us, these experiences what we’re going to face, what they may look (like) and I stick by that. And that is exactly what it will look like.
“We need to make a decision and try and help this group, this young group, who at times are struggling for air.
“Every one of us – me, my staff, the fans – we need to make that decision, really.”
The performance against Liverpool underlined the need for new faces before the deadline after what has been a quiet summer.
“I don’t know (if there will be more signings),” the deflated Cherries boss said. “We’ve been trying to do that.
“There’s millions of reasons why and there’s loads of circumstances why this is not just as straightforward as not being able to sign players because players don’t want to come or whatever it is.
“There’s a lot of issues here for the reasons why we’ve not been able to do that and it just depends whether them issues resolve or we make a decision. That’s it, really.”
