Lallana was outstanding in victory at Cardiff City.
"It was an unbelievable performance. It's week in, week out," Rodriguez told the Daily Echo. "He's a great player and it was nice he set me up."
Only 48 hours earlier, on Christmas Eve, Lallana had married his fiancée, Emily Jubb, making it a week to remember for the 25-year-old.
"When I went in the next day I just congratulated him," said Rodriguez. "I'm so happy for him, they're a lovely couple. "It's a nice thing. He's a good lad and he's got a good family."
