Andy Murray knocked out top seed Jannik Sinner to reach the Stockholm Open quarter-finals and said "it's probably my best win this season".

The Briton, 34, was fired up and focused against the 20-year-old Italian world number 10 in a 7-6 (7-4) 6-3 win that was one of his finest since his comeback from two hip surgeries.

Murray will face American Tommy Paul for a place in the semi-finals.

"Now I'm in the quarters, I want to have a deep run here," he said.

Speaking in his courtside interview, a delighted Murray added: "I want to keep it going now."

Murray's only other win over a top-10 player this year was against Poland's Hubert Hurkacz in Vienna in October and the Scot has also only reached one other quarter-final on the ATP Tour in 2021 at the Moselle Open in September.

He is joined in the last eight by compatriot Dan Evans, who beat Spain's Alejandro Davidovich Fokina 7-6 (7-5) 6-2.
