England batsman Jonathan Trott is adamant that his best form is still to come after mixed performances in the opening two Tests of the Ashes.

The 32-year-old scored 48 and 58 runs in his opening innings of the first and second matches respectively, but was called out for a duck in both of his following stints at the crease.

When asked if his best is still to come this series, Trott said: "I hope so. I've felt good, actually. Sometimes you score runs and you're not feeling at the top of your game. I feel like I'm playing pretty well and it's been nice to get a couple of good partnerships, like with Belly at Lord's in a tricky situation, I suppose, at 28 for three.

"We put on 99 and he went on and got the big score that I would have liked. But there are still three games left and personally it would be nice to contribute in a similar way. Anybody can get out quite early in their innings, I suppose. You haven't contributed for the team but, if you get 50, at least you have done something towards the team effort - although on a personal note it is pretty upsetting because you have done all the hard work and you're feeling pretty good.

"It's frustrating but I feel in the past that I have contributed and the side has been successful. Other people like Joe and Ian have stepped in, perhaps it is my turn for the rest of the series."

England face Australia in the third Test of the Ashes at Old Trafford on August 1.
