"David scored 16 goals but didn't start in 18 matches last season so that is a terrific return from him.
“He has always been a great finisher. As a youngster he was always scoring from any angle and from inside and outside of the box. It is good to see him back to that.
"I said to him that in terms of improvements and making progress you have to add things to your game. Goalscoring was the area where I felt David could improve last season.
“He took the challenge on board and it was much better last year. He became a terrific finisher again and that's good for him and for us.
"He was back to the goalscoring form of three or four years ago and the confidence was back in and around the penalty box again. That's good to have as a back-up to your main strikers."
"It was a great shame that injury de-railed it all for both ourselves and England. If David had been fit for us in the Champions League semi-final in Germany against Bayer Leverkusen then we'd have got through to the final and could have won it."
