Okay, here's the figures - based off reported / confirmed fees.
OUTS (since July 1st 2016, not inc. loans)
Stones - £47.5m
Gibson - £2m
Oviedo - £4m
Total: £53.5m (approx)
INS (since July 1st 2016, not inc. loans)
Stek - £850,000
Gueye - £7.1m
Williams - £11m
Bolasie - £25m (some will say £28m)
Calvert-Lewin - £1.5m
Lookman - £10m
Schneiderlin - £24m
Total: £79.5m
So yeh, approx £26m net spend on transfers. I hadn't included Clevs on that though so when he 'officially' goes (July 1st) that net spend will be down to just the £18m (approx).
Got my maths mixed up in the op so I apologise for that. My bad.
Don't you normally say Bolasie was 23m?
