yes also Cilic when he's in a "few errors" day, both Berdych and Cilic have a very good return to attack second serves, and it's useful against Murray, although his second serve has improved.
Another one who has a good H2H against Murray is Baghdatis, and he also attacks Murray's second serve.
Another possibility is to grind out Murray : Ferrer can do it for instance.
Ferrer can do it on clay, but not on other surfaces. Cilic is has only ever beaten Murray once out 6 or 7 tries, so I don't think he's a good example.
