Suarez hit a hat-trick in victory over West Bromwich Albion.
"It was a performance that just oozed class really," Scales told talkSPORT.
"A lot has been made of Suarez and Sturridge. Is this a great partnership? Well it showed all its class and quality yesterday. Suarez was unplayable and Sturridge does what he does really, really well with his movement and pace."
