Martin O'Neill has signed one and got the other on loan. It will all go through in January. Can't guarantee it but just been told by a mate at the Villa.
If so, i can see aston villa becoming a big side. Martin o'neill has done wonders there, he is a quality manager that should have been snapped up by england. I'm not sure whether this rumour is true, they are both not regulars, so it would figure that they could go out on loan.
From what they were saying about Silvestre earlier in the season I believe his contract is up soon and that Manure were going to cash in on him before losing him for free.. so silvestre as the buy and Brown as the loan would be my guess also.
