Manchester United boss Louis van Gaal says he needs at least two more players to complete the squad for next season.
The Red Devils have already added Memphis Depay, Matteo Darmian, Bastian Schweinsteiger and Morgan Schneiderlin to their squad so far this summer.
But the Dutchman revealed that more players are expected to join before the end of the transfer market.
"No, we are not finished yet, I think," van Gaal told MUTV.
"It is what I have said already in many press conferences.
"We need a balance in the selection and I think we still need to improve at least two positions and we shall do that when it is possible.
"But we shall only buy when the player can give a contribution to our level.
"And, of course, that is in the eyes of our staff, but I have to have confidence that he can cope with the rhythm of the Premier League."
