Frank Lampard has claimed gruelling gym sessions are the secret to Christian Pulisic’s impressive spell of form.

Since the restart, the United States international has been churning out impressive displays on the field of play.

Pulisic has nine goals and nine assists across all competitions in his first season at Stamford Bridge, despite being sidelined for two months with an abductor injury.

The Chelsea ace has really found his feet since the Premier League restarted in June, scoring three goals and supplying three assists while also winning two penalties in his last seven league outings.

He said: “He has worked a lot with our strength and conditioning coach, Adam Burrows, who is fantastic.

“They have worked a lot together, but it is Christian who has to take on that responsibility and he has.

“Physically that has helped him. Also, just his talent coming through.

“Looking forward, I probably want to see more of what he has shown in recent times, which is goals and assists, because that is what the best in the world do in that position.
