Hes a great all around CM IRL so im guessing hes simular in the game so for £9.5m i would say yes hes probably worth the signing if doesent work out you can always sell him for over £10m
Not worth it. You can buy many other younger players for cheaper who will soon surpass him in quality and obviously also demand lower wages. Otherwise spend more and go for Khedira for 17 or so million (unless he's already signed for Chelsea) as he's twice the player Ramires is.
Khedira is the guy you're looking for, playing as Chelsea I sold off Ramires and bought Khedira, commands high wages but worth it. Ramires' avg rating after a season was 7.15, Khedira's is so far 7.6
