The England international was making only his second appearance since April following a lengthy spell on the side-lines through injury, and his absence has been truly missed.
Speaking to Sky Sports on the matter, Rush feels the striker’s return will give the team a real boost of confidence and implored the Reds to keep him fit and utilise his abilities as frequent as possible.
"It's great to have Sturridge back," Rush explained to Sky Sports. "When you have someone like him back it just gives the other players a bit more confidence.”
"He's been a big miss for the last year or so because he's a quality player. You have to keep him fit, get that confidence back in the team and keep creating chances and scoring.”
Following the disappointing 1-1 home draw with Norwich City, it took all of three minutes for Brendan Rodgers’ men to get off the mark against Villa with James Milner firing the hosts ahead.
Yet, a much-needed fluent performance was still a long way away and the hosts were indebted to Sturridge as he clinically kept the visitors out of reach.
The 26-year-old scored both his goals in the second period, having taken five shots in total with four of those making Brad Guzan work in the Villa goal.
Rodgers has a tough task ahead of him in getting the best out of both Sturridge and fellow striker Christian Benteke, with the potential there for a potent partnership capable of firing the Reds to a top four spot.
