Chelsea manager Antonio Conte has said that Paris Saint-Germain should not be criticised for spending a world-record £200m to acquire Neymar this summer.
The Brazilian forward completed the mega-money switch from Barcelona last night in a deal that more than doubles the previous world transfer record.
The Premier League champions have already broken their own transfer record so far this summer, splashing out more than £58m on Alvaro Morata, but Conte believes that three-figure sums could become the new norm in the years ahead.
"[The Neymar deal is] a difficult topic," he told reporters today. "I think Neymar is one the best players in the world. This type of player finishes their career in the same team. If they look to change we have to be ready to accept this kind of money.
"For a normal player you have to be ready to spend £40m to £50m. If you want to buy a top player you have to be ready to spend this kind of money. It's an impressive amount of money, £200m. If PSG is able to do this, why not?
"Now for us it's very important to try to improve our squad in the numerical aspect, we have a small squad.
"Buying only one player is not enough, we need more. We need more players, perhaps not at the top level like Neymar, but we have to improve the quality and numerical aspect. We have few players."
As well as Morata, Conte has also brought in Tiemoue Bakayoko (£40m), Antonio Rudiger (£29m) and Willy Caballero (free) to Stamford Bridge so far this summer.
