It was Aspas' first competitive goal for the Reds.
Toure told liverpoolfc.com: "This goal will change him, definitely. Aspas did really well and we are all really happy for him.
"He hasn't played many games since he came here but he scored a great goal for us. The Premier League is a tough league - it is the best league in the world.
"He's a young striker who was fantastic for Celta Vigo. We know what he can do, he just needs time. It's very important for a striker to score goals - their confidence comes from scoring goals."
