Manchester United boss Louis van Gaal says he already knows who will leave and who should join during the summer transfer window.
The Red Devils finished their campaign with a goalless draw away at Hull City, sealing a top-four finish ahead of Tottenham Hotspur in fifth.
They will be in action in the final qualifying round for the Champions League when the new season kicks off in August.
"I think you have seen that very well," van Gaal said.
"It was a special atmosphere - I have never seen fans of a team who are going to be relegated be so supportive until the end. Their fans and the players were very positive, which made it difficult for us to equal their aggression and their motivation.
"They were fighting for a rescue, but we were fighting for a dream, to finish the season the proper way. That proved to be difficult, as you have seen.
"But still, we have earned a clean sheet, also with another goalkeeper. At the end, this game was not so important anymore because Newcastle won, which meant everyone had done their sporting duties.
"[The transfer market?] Yes, of course, I go on holiday but I have contact with Ed Woodward every day as he is doing the negotiations.
"We know now who has to go and which players we want to bring in, but that is a process, so you never know.
"These things are dependable on different parties - the club, the player and Manchester United of course. It shall be a heavy [busy] holiday! [smiles]."
