Shelvey feels he learnt much from the Scot's experience.
"Barry Ferguson is a top player and I didn't realise how much history he's got until I looked him up on Wikipedia!" said Shelvey. "He's a great leader and a great player. You have to listen and learn from people like him.
"I've been in the game for three years and someone like Barry has dealt with being a footballer for his entire career.
"Also Ian Holloway is very different to previous managers I've had but he's been first-class with the way he's handled me.
"I'm quite a feisty character on the field because I want to win, and he's given me a boost of confidence that I needed to take back to Liverpool.
"It's been a pleasure playing for him, and I think I'm going back fitter and stronger.
"I think I did well at the club and I hope I've given the fans something to remember."
