Rush told talkSPORT: "We know Luis Suarez is a great player. With Sturridge, the manager has given him confidence and belief. Daniel Sturridge can be anything [he wants], he’s got everything going for him, he just needed that confidence.
"I think they’ll get even better. You’ve also got [Robin] Van Persie and [Wayne] Rooney, they’re two great players and I think it’s good you can put Suarez and Sturridge in that category as well."
