Marco Silva says Hull City need to learn from their mistakes as they prepare for life outside the Premier League.
The Tigers' Portuguese boss gave the Tigers a chance of avoiding relegation after a positive run of results following his arrival in January – but yesterday's 4-0 defeat at Crystal Palace confirmed an instant return to the Sky Bet Championship.
Silva, 39, said the foundations for the club's relegation were laid in pre-season.
"We tried to do many things in January but it's not good to be signing six or seven players in January and losing two. You should be doing that in June, in pre-season. You need to prepare better," he said.
"The most important thing is for the club to understand what they did in a bad way, to prepare. You start to win or lose a season ahead one year in advance.
"It's clear we did our best, to try and play at a higher level, and to fight until this moment."
City were early season favourites for relegation, with Mike Phelan as their caretaker manager, and only 13 fit senior players.
They were bottom when Silva took over and, while 14 points in 10 games took them out of the bottom three, a dip in form at the end of the campaign sealed their fate.
Silva's future is now the subject of debate, with the previously little-known Portuguese having established a reputation for himself. His contract expires at the end of the season.
He said: "Now is not the moment to talk about the future of the manager. It's about the future of the club. I will talk to the board and the chairman first, talking inside the walls of the club. Now we have to analyse it.
"I will give the board and the chairman my opinion, about what they need to do differently to make sure this doesn't happen. We'll talk in the next few days. We will talk before the Tottenham match.
"We'll see (if I will be manager next season). I have enjoyed these four months in the Premier League. That was one target I had in my career, and we tried to do our best.
"Now it's time to be calm and see what is best, first for the future of the club, and also for my career as well."
