I'm going to say Jorginho & Griezmann. £125m for both. I think we'll sell Maffeo (already £8m), Zincheko (£10m), Roberts (£15m), Bravo/Gunn (£3m/£10m), Mangala (£8m). Potential £50m+ coming in plus £40m winning the league, we'll be spending net fuck all in the grand scheme of things.
* edit just read we got £150m from the Premier League. Wow.
