About time to be fair.
When you see how well Loftus-Cheek and Hudson-Odoi have been playing it really does give faith that there are some really good players with lots of potential in their youth squads or out on loan.
Would be like being chucked in the deep end for some youngsters to play a whole season though.
Having said that, some loan players could still do some kind of job in the league:
Batshuayi, Morata (20/21 season), Abraham, Pulisic, Baker, Zouma, Bakayoko who have more experience than just a youth player off the top of my head.
Replacing Hazard is always going to be difficult even without a transfer ban.
