Which is exactly the reason we should not be buying within the Premier League unless we can get a good deal - i.e Pelle who has 12 months left and doesn't look like signing a new deal with Southampton. They will be willing to cash in and move on to another target, that is the way they operate.
We should absolutely set our stall out and buy a one big statement player, 30-35 million on a centre mid or striker to partner/replace Lukaku.
Then we start looking at cheaper deals in the 10-15 million range. Janssen, Milik, Bazoer. These will be the types of players Koeman targets as he's had his eye on them for Southampton.
Of course we still need a keeper and this will cost between 15-20 million, if we want actual quality and not overhyped dung like Mandanda or Krul.
