Yes and no. Tarkowski may ask for up to£10mill sign on fee(this will be his last one) and get it dependent on how desperate a club is for his services = £28.7mil at a start off age of 29 and no resell value up to the age of 33.
Konate total of £50mil but with a start off age of 22 on a four year deal he leaves after three to one of the so called big four or european big boys if successful with a figure that would dwarf his signing fee to reinvest.
Too long we have tried and failed to buy established players and failed miserably, the introduction of a nearly proven may be better than an only proven at a relegated side style of player.
There are far to many variables in transfers, the foreign player (Moise Kean) fails, the home grown but older player does not perform without his sidekick(Cottee and macKevennie), but as a supporter I have a gut feeling of who i want at Everton and for me its not Tarkowski. I'm not saying I'm right or wrong just giving my two penneth.
