"There's good competition here for the full-back spots. I'm up against one of the best right-backs in the world in Glen [Johnson]. But training with him every day helps me progress and it's great for me to be able to learn from him.
"If there's an injury I've got to be ready to slot in and I can play on either side at the back."
The defender played in all three of Liverpool’s pre-season matches in their tour of the United States, against Toronto FC, Roma and Tottenham, and praised the impact Rodgers has had since his arrival from Swansea City over the summer.
"It was great to be out there [on the pre-season tour] and be part of the training camp,” he added.
"I like the way the new manager is doing things and his style of play. I've learned a lot and I'm looking forward to learning more from him.
"He has come in and given all the young lads a massive lift. He has said that if we do well there will be opportunities for us and that's good to hear.
"It was great to hear his plans and everyone wants to be a part of it."
