Dorrans hails Scharner West Brom impact
He says there is no substitute for the wealth of Barclays Premier League experience he brings to the team.
"He's a big character," Dorrans told the WBA website.
"He does a lot of moaning in training and games but he's got great experience and that's what we need because we've got a young squad.
"He's played in the Premier League, he knows what it's about and you can see what he brings to the team - it's good having him alongside you in the side.
"He took us out for dinner to a restaurant in Sutton a couple of weeks ago.
"As a new signing he wanted to take us all out and get to know us.
"He paid for all of us - he made us have the full monty and it was good to get all the lads out."
