Roy Keane aimed a shock attack on Luke Shaw after he dismissing the idea of one of Chelsea's new signings making an impact.
Chelsea have spent Ā£185 million on a total of 10 signings so far this summer under new manager Enzo Maresca, with their approach heavily criticised by many.
Their most expensive addition was the Ā£54 million capture of Pedro Neto for Wolves.
He has penned a seven-year contract at Stamford Bridge and was presented at the stadium at the weekend.

The former Braga player has been viewed as one of the best players outside of the top six for a while now and many have been waiting for him to get a move to a bigger club.
Yet his injury record is a serious concern and former Manchester United captain Keane is convinced he will flop at Chelsea.
On the latest episode of 'Stick to Football' powered by Sky Bet, Arsenal legend Ian Wright suggested Neto could be one of the signings of the season.
But Keane scoffed at that prediction and compared Neto to Shaw, who has been plagued by muscle problems in recent years.
Keane said: "No! Heās always injured! F*** sake. Heās like [Luke] Shaw.
"Heāll add to the chaos. Heās going to add to the chaos. He will run everywhere and then spend six months on the treatment table with a hamstring injury."
Neto played 20 times in the Premier League last term but had two extended spells out injured with hamstring issues.
He missed eight games in November/December time before coming back into the fold, only to be out again for a total of nine games towards the end of the campaign.
The Portugal international did make a sub appearance against Liverpool on the final day.
Chelsea begin the new season against champions Manchester City on Sunday.
