Gallacher for me is very very like Lampard was at the same age, question would be is does he have the improvement in him which Lampard did as well - a 22 yo Lampard was way inferior to the one at 26+ as he added so much intelligence to his game
For me I really rate Gallacher hugely, think handled right he could go on to be very much a Lampard version 2, he has that ability to see space you don't get with many and can't teach, natural finisher and personality wise seems to have everything you want to see in terms of making the most out of what he's got.
I agree about Cowill, looks talented, but cb right now post Tarkowski I feel is fine, good loan sorted for Braithwaite which hopefully sees him develop to be a part next season of the team, Godfrey I think post COVID/injury will improve a lot especially having good coaching staff and Tarkowski here to learn from, so don't see the point of adding a 19yo who may not be ready yet.
Broja - dunno if he'd come here to be a backup to DCL tbh and certainly we can't spend 30m on a backup.
Ampadu is weird as he's not nailed down a position yet, DM seems his natural one but think last year on loan he pretty much played it as a cb.
Then you have Gilmour, plus the young AM we where linked with the other day - who I'd never heard of tbh and who knows who else is there under the radar at Chelsea as honestly never heard of any of the players above two seasons ago either - same with James and Mount a few years before that as well really.
