I can see the assessment of 'how well/badly we've done' this window will include both outgoings as well as incoming.
Here's the outoings story :
Ndombele @ £200k pw = £10m pa and with 3.5 years left on contract £35m
Lo Celso @ £90k pw ......... £4.5m pa and with 3.5 years let on contract £16m
Dele @ £180k pw ...............,,£9m pa and with 2 years left on contract £18m
Total ..... £470k pw ............ £23.5m pa ..........................................................£69m
We could get a couple of players for free (or even a top striker such as Dusan Vlahovic) with wages saved over the rest of their contracts.
If all 3 midfielders left in January, given their limited playing time this season, would we be able to cover their games with just one incoming midfielder - possibly with Harvey White/Nile John/Alfie Devine getting minutes as well ?
