Reina will go into Sunday's clash with Tottenham at Anfield on a high after producing his best performance of the campaign in last weekend's 4-0 rout of Wigan.
He said: "I'm happy I helped the team. I did my job. There will be some mistakes along the way but there will also be games like Wigan.
"The whole group is trying to find the right balance. We will get better, I'm sure of it."
