Adam Lallana believes it doesn't take much time for footballer's to start missing their job.

The Liverpool midfielder has returned to Melwood for pre-season training after he was granted an extended break because of his appearances for England.

"I've had a great summer. It's always nice to relax with your family and recharge the batteries," Lallana told the club's website.

"But I'm more than ready to come back now. You get withdrawal symptoms! I've slotted back into club life as normal.

"Everyone ticks over in the summer – it's important. We're given a programme and it's important you stay ahead of the game as much as you can."
