England rugby coach Eddie Jones admits his future lies in the hands of officials at Twickenham, but remains convinced he is the right man to lead the 2003 world champions to the next World Cup.
A fifth-place finish sealed by Saturday's 32-18 defeat in Dublin completed a dismal Six Nations that has placed the Australian's reign under intense scrutiny.
The Rugby Football Union's customary post-Championship review will begin in the coming days with no timeframe set for its completion.
"Everyone is entitled to their opinion and I'm sure they're angry. We expect to win and we expect to play better than we did," Jones said in addressing the frustration of supporters.
"No one is more disappointed than the team and ourselves with what happened and the fans have got the right to be disappointed. We're gutted by it."
England entered the Six Nations as champions after compiling an eight-Test winning run which also secured the Autumn Nations Cup, but cracks were already evident as performances failed to match results.
"Unfortunately I thought we were due for a period like this. Every team goes through it," Jones added.
"International rugby, particularly at Six Nations level, you get to a certain stage and the success makes you a bit weak. You need to fight through that.
"It's hard to be at the top of the tree all the time. And so the team goes through cycles of success and cycles of failure and I think that's a normal part of sport."
Senior players Maro Itoje, Mako Vunipola and Jonny May have given Jones - the world's highest paid rugby coach - emphatic endorsements, insisting it is the players who must be held accountable for the losses to Scotland, Wales and Ireland.
"Tactically, physically, mentally we're prepared extremely well. We have the best players, staff resources, players I feel. This one is on the players, so we need to sort it," May said.
"I pretty much have felt sick for the whole lot of it (Six Nations) because it's been tough. That's a positive because I care and the team cares. It means a lot to us.
"The regret is that we couldn't make the people at home who watch us and expect us to win, happy. And I'm sorry about that."
