Leeds United midfielder Jack Harrison says their fitness levels were key to thrashing Newcastle United.

Harrison hailed the manner of their 5-2 triumph.

“We've had a few rough games and we were really hoping to come back and redeem ourselves," Harrison said on Leeds' official website.

“We knew how important it was to come out strong, be aggressive and play our usual game and we did exactly that.

“We want to be as aggressive and intense as we can. If you look at all the players making long runs in the last few minutes, it shows our fitness levels and how we want to play. We know how important it is for us to do that."

Harrison capped a memorable night for the home side with his left-foot strike from distance after driving forward.

“It was just a spur of the moment thing," Harrison added. “I didn't really think about it too much and I think when I don't think about it too much, that's when the best things can happen.

“It was really fortunate to get that one at the end, we're always trying to be intense and play until the final whistle."
