Briggs is expected to start today in the Premier League playoff against Crystal Palace.
He told fulhamfc.com: "It's a much-faster pace in the Championship; you get a bit more time on the ball in the Premier League. But I'm comfortable at that level, I've been there before with Bristol City and Peterborough United and I'm accustomed to the pace of it.
"The manager's quality, he's class. He's good with young players and we've got a young squad - he's always talking to us. He joins in training and teaches us new tricks. He's still got it in training; I reckon he could still play in the Premier League!"
