First we should buy the players we need instantly- If we stay with 3-5-2, we shall get Jovetic/Sanchez and a LM/LWB (40-45 million). If we change to 4-3-3, we shall get both Jovetic and Sanchez/Robben for the wings and Obiang for backup (60-65 million, but we can sell few more players so it's nearly even).
Both are totally possible.
