Roma fullback Rick Karsdorp says they must build on their derby win against Lazio.

The Giallorossi are targeting fourth place with their form back on track.

"We've got to build on that, because it was our best performance of the season," Karsdorp told Sky Italia.

“We want to fight to win the Conference League and we're still in the running for fourth place in Serie A too."

The Dane also spoke of Tammy Abraham's goalscoring.

He added: “He is a special striker. I've got four assists for him, but those are destined to grow, because we are perfectly in sync."
