Chelsea's transfer business has been criticised after they were told they have been overpaying this summer.
The Blues have not been shy in the transfer market this window with six new arrivals.
Frank Lampard was unable to make any signings last summer but has been making up for lost time
The new faces include Timo Werner, Kai Havertz, Ben Chilwell, Thiago Silva, Malang Sarr and Hakim Ziyech.
It has seen Chelsea spend over £200m - though the arrivals of Silva and Sarr came on free transfers.
And the London outfit are not done yet with a goalkeeper and Declan Rice in Lampard's sights.
Improving the backline has been a priority of the Englishman's this summer.
But a top-ranking agent has slammed Lampard's business, insisting he has overpaid for players this year.
“£80 million is not getting you an established superstar this summer,” they told The National.
“Clubs don’t want to sell or need to sell – yet.
“With Madrid and [Barcelona] not buying, Chelsea have seen a gap and gone for it, but they’ve spent less in recent seasons because of a ban and they’re also owned by one the richest men in the world.
“They’re also overpaying to bring players in.”
Meanwhile, former Blues star Craig Burley has insisted that more arrivals are needed at Stamford Bridge.
“Thiago Silva is going to need an oxygen mask because there is only N’Golo Kante in there who has got any defensive qualities,” he said.
“That’s going to be the difficulty for Lampard, striking the balance.

“Mason Mount, who really flourished in his first season in the Premier League, is an attacking player, Kai Havertz played a lot of the season at Leverkusen as a striker, and then you add the front three [Werner, Ziyech and Christian Pulisic] in and it’s ‘over to you N’Golo Kante’ because nobody else is going to be defending!
“Striking a balance with [Mateo] Kovacic or somebody else in there is going to be key.
“Chelsea had one of their worst seasons defensively last year, they lost a heck of a lot of goals, so Lampard knows that he needs to make sure he solidifies his back line, which was a big problem for them."
