The Blues unveiled their newest January signing on a £16million loan deal on Wednesday.
Timo Werner was the last player to wear the No11 for Chelsea with Didier Drogba, Dennis Wise and Damien Duff also previous inhabitants.
“He’s a quality player,” Potter said.
“He can make a difference in the final third of the pitch. He’s young but has still had a lot of really good experience. He’s just a quality player that gives everyone a lift.
“We’ve been aware of [him] for a while – these kinds of things don’t happen quickly. The injuries have sharpened the focus a little bit. Still it’s nice to get him here, to get him training today. That’s a positive for us.
“Then we’ll see for the game on Thursday. We’re waiting for confirmation.”
