I would speculate that everything has been agreed on Saturday, but perhaps Collo wanted to sort a few bits and bobs out at home (in spain) first.
We have already been informed that an agreement has been made on price, we were also told that personal terms had been agreed prior to a price being agreed. All thats left is the medical today and then he is signed.
I'm guessing all will be tied up before 16:00 today.
As for Wise & Co, I dont think they will have been working on other deals rather than concentrating on one that has pretty much been sorted since Friday Night/ Saturday morning.
