Even if we get rid of Torres, you've got to reckon that we'll get another quick, tricky striker in rather than a big guy like Falcao or Cavani. No point in changing our style and buying a bunch of players to suit a game along the ground, then jacking it all by buying a striker that doesn't suit us again.
Particularly when Lukaku's coming back next season. You've got your all-round striker (Torres) and your big man option (Lukaku), so getting a tricky, quick striker makes sense.
