DUBLIN -- Jose Mourinho insists Neymar's world-record move to Paris Saint-Germain is "not expensive," but added the consequences of the fee could be.
The transfer more than doubles the record fee Manchester United paid for Paul Pogba 12 months ago, but Mourinho hinted it will be money well spent.
Speaking before the deal was completed, he said: "When we paid that amount for Paul I [said] that he was not expensive. Expensive are the ones that get into a certain level with a certain quality, I think Neymar is going to happen the same, I don't think he's expensive.
"I think he's expensive now because you are going to have more players of £100 million and £80 million and £60 million and I think that's the problem because Neymar is one of the best players in the world.
"Commercially he's very strong and PSG thought about it, so I don't think the problem is Neymar, it's the consequences."
Mourinho has spent close to £150 million during the summer to bring Victor Lindelof, Romelu Lukaku and Nemanja Matic to Old Trafford. But with a month of the transfer window still to go, the United manager admits he would like one more new arrival.
He has already said he wants another attacking player with Inter Milan winger Ivan Perisic heavily linked.
Mourinho added: "The squad is good and as I told a few months ago I was hoping for four players to improve the squad and the club did a fantastic job by getting three of them which is difficult in the crazy market where we are now.
"To get three out of four I thank the club for that, I would be happier if they give me four of four but they did a great job."
