Let's say it's ten. Spend that on Sako from Palace and Murphy at Newcastle. We would be much stronger with them alone. Get Irvine from Burton by swapping for a couple of loans if you want another central midfielder. Watkins on a free from Barnsley gives you more wide options.
We must be able to get 15-20m for Amavi & Vertout alone; we shouldn't be losing money on either. Use the market sensibly and we've got more than enough to get out of this league.
Meanwhile, Man City, Man Utd and Liverpool spent a combined £70m between 2nd Feb 2016 and 31st Jan 2017. Just on agents fees.
