This report in Marca is quite clear. It says that the agreement between Silva and MCFC is 'total', as is a deal between the two clubs, quoting reports from Spanish radio station Onda Cero.
This report, in Diario AS goes further. It says that the deal is for five years, at €5m/year (roughly £80k/week). It suggests that Roque Santa Cruz might be thrown into the deal, but says that everything is agreed and will be formalised soon.
Of course, nothing can happen while David Silva is in South Africa but unless Chelsea match our bid we might well see firm movement on this soon.
