His minutes to goals ratio has been decent enough in a foreign league where Ronaldo isn't bagging half as many as he did in Spain. His wages are only that high as he was on a free. So the 21 million it has cost Juve, they will get that back in a transfer fee and Ramsey will know he will have to take a pay cut if he wants to play.
This is why we can't have nice things if we turn our noses up at someone like Ramsey. He would instantly transform our midfield. There is a doubt injury wise with him but when we signed Reid and Gray in the 80's that was a similar risk.
