Chelsea have put forward a proposal to the Premier League requesting an increase in bench size from seven to nine, which would see an increase in options for managers during matches ahead of 'Project Restart'.
This would see squad sizes on matchdays increase to 20 from 18 as Premier League shareholders are set to meet on Thursday ahead of a vote on June 11.
The Premier League is also going to discuss whether to allow managers to increase the use of substitutes from three to five but that is not something that was first proposed by the west Londoners.
