Louis van Gaal is expecting a busy summer of transfer activity at Manchester United having concluded the season.

The Red Devils finished the campaign with a 0-0 draw at Hull City, a match that may well have been the final game for a number of existing players.

Radamel Falcao is among those almost certain to depart, with an understanding that the Old Trafford hierarchy have decided not to make his move a permanent one. Van Gaal, who ommitted the Colombian from the squad, refused to confirm the news in the aftermath of Sunday's match however.

"I don't say if Falcao will go today," said the Dutchman. "Today is about the game and not the decisions we have made. You will hear it at the proper time and when Manchester United want."

Several more players could follow out of the exit door at United.

Doubts remain over Anders Lindegaard, Jonny Evans, Rafael, Angel di Maria, Adnan Januzaj, Robin van Persie, Nani and Javier Hernandez.

Van Gaal will look to clear out a few of those players to make way for new signings, but the former Barcelona coach knows he may not get his own way.

"The transfer period is a process. I know which players have to go and which have to come but you never know if they go or if they come because it will depend on a lot of aspects," he said.

Van Gaal will fly to his villa in Portugal this week after a draining year.

The 63-year-old only had a two-day break between the end of the World Cup and taking charge of United. He is looking forward to a holiday but will have his phone close by his side.

"I go on holiday but I have contact with (executive vice-chairman) Ed Woodward every day as he is doing the negotiations," Van Gaal told MUTV.

"It shall be a heavy (busy) holiday."
