That is the view of ESPN FC pundit and former West Ham and Newcastle goalkeeper Shaka Hislop.
Chelsea have lost their appeal against a two-window transfer ban applied on them by Fifa.
The Blues are now set to take the appeal to the Court of Arbitration for Sport.
In the past, taking the case to the CAS has helped teams who have had transfer bans, delaying it to allow the club to bring in players until a decision is made.
But Hislop says if that did not happen, Sarri must look at using some of the players he has out on loan.
Chelsea have had 41 players out on temporary deals this season.
Hislop doubts whether any of them would get into the starting XI at Stamford Bridge just yet.
However, he selected winger Victor Moses, centre-back Kurt Zouma and midfielder Tiemoue Bakayoko as three who could bolster Sarri’s squad.
