From what I can see it's up to £8mill, after all Torres cost us £37 according to reports at the time (strangely Sky & the BBC websites now report £20.8mill, have we had a word?).
BTW, has anyone not wondered why they've signed him on just a 3 year contract (with Fulham holding the option for a 4th)? If they're getting such a bargain why haven't they insured their investment with a longer term one? Obviously Tosin would need to agree to that but I think it points more to Fulhams thinking on his worth.
Just seen that the MEN claim a 20% sell-on fee.
