U.S. international Christian Pulisic has said he is happy at Borussia Dortmund amid renewed rumours he could join Liverpool. Following his breakthrough season at Dortmund, Pulisic has once again been linked with Liverpool, who made an attempt to sign the winger last year. However, Pulisic -- who signed a new contract in January -- has said he has no intention of leaving the Westfalenstadion at this stage. Asked about the Liverpool speculation, the 18-year-old told Sport Bild: "Yes, I have read that as well. What can I say? I'm focused on the start of the season. "I'll lay it on the line for you: I am not thinking about changing clubs. After all, I only signed a new deal through to 2020 in January. I am very happy at Dortmund." Pulisic played in 43 competitive games for Dortmund last season, scoring five goals and providing 13 assists. He has enjoyed even greater success for United States, scoring seven goals in 15 appearances, with five of those strikes coming in World Cup qualifiers. "Football might not be the biggest sport in America, but the popularity of our soccer keeps growing," he said. "It would be fantastic if I could contribute my part to inspire kids to play football."
