Rodriguez capped a wonderful personal performance at home to Fulham at the weekend by making one goal for Lambert and heading home the other in a 2-0 win.
Meanwhile, Lambert, 31, has already made his mark at international level this season by scoring for England against Scotland and Moldova.
And Lallana said: "It's a pleasure to play with both of them. I've played with Rickie for four or five years now and feel like I know his game inside out and when Jay Rod's playing with confidence like that, there are not many better than him.
"He had a great first season and played without a care in the world against Fulham.
"He went on several runs, got his goal, went close with the bicycle kick... he works so hard so it's great to see him play so freely.
"He's been asked to play in numerous positions but goes out and gives 100 per cent regardless of where he's playing.
"He won't sulk, he won't moan. It's a credit to him that he can play in different positions and formations and just get on with it and give everything, no matter what.
"He's a top lad, getting the goal on Saturday was just what he deserved."
