Ramsey believes there is even more to come from the £52m signing.
"He's very technically good, he's very clean with his touches and his link up play and he's a great finisher," the Welshman said.
“We've seen some fantastic finishes so far from him and I'm sure there will be many, many more to come as well, so it's exciting times for him personally and for us to have him here.
“I think his understanding is pretty good so far. He likes to come a bit deeper sometimes and try to link up the play and feed players in.
“He makes those darting runs in behind as well, so he's very good to play with and hopefully we can link up well throughout the season."
