Milan's mystery Mr X signing won't be Cesc Fabregas after he completed his expected move from Arsenal to Barcelona today.
The Spaniard has joined the Nou Camp outfit for £30m, but that fee could rise by a further £5m depending if bonus clauses are activated.
Fabregas, who has signed a five-year contract with the European champions, was associated with the Rossoneri earlier this summer.
Some were suggesting that he could be the midfielder which the Italian champions have promised to sign before the campaign starts.
