Ole Gunnar Solskjaer says the buck stops with him following Cardiff's relegation from the Premier League.
The Bluebirds' return to the Championship was confirmed by a 3-0 defeat against Newcastle last weekend, making today's final game at home to Chelsea an irrelevance in terms of survival.
Solskjaer took over as manager in January after Cardiff chairman Vincent Tan dispensed with Malky Mackay's services, but he was unable to inspire a climb out of the bottom three, and Cardiff face Chelsea as the league's bottom team.
"I am the manager. I will take the blame," Solskjaer said.
"I didn't make the impact on the results I hoped for. I came in hoping to make a difference and we could move up the table, but it didn't happen.
"We haven't performed very well to stay up, and that's the reality. We have not been good enough.
"We have got to give the fans a good last game, and then we will look towards next season."
Solskjaer revealed he had spoken with Tan in the wake of events last weekend. There are no indications that the Norwegian will not still be in charge, come the start of next season.
"I have got no other signals than planning for next season," Solskjaer said. "The key is to start the season well.
"You have to learn from your mistakes as a player and coach. I am a better manager now than when I came here. We came into the unknown this season, and the majority of the players didn't know much about the Premier League."
Cardiff will be without Juan Cala for today's visit from Chelsea after the defender was handed a three-match suspension.
The Spaniard was sent off in the Bluebirds' 4-0 defeat at Sunderland last month for denying Connor Wickham a goalscoring opportunity, but this punishment related to his conduct as he left the field and made his way to the players' tunnel.
