"The top-order felt the pressure of not scoring, that's what you have to do in Test cricket, absorb pressure. A bit more application from the batsmen and it would have been better," Dhoni said after India lost the fifth Test by an innings and 244 runs.
"Right from the start, our batsmen never really performed, the lower order helped out. That camouflaged the performance of the top order, just scoring 150-60 runs will not be enough to defend against the home team," he added.
Asked about the English conditions, Dhoni said, "It's demanding but the wickets were good, nice pace and bounce. In the overcast conditions the fast bowlers get swing and the English bowlers were very consistent."
The Indian captain though hoped that his young players will take their lessons from the series and play better when they come to England next time.
"We've lost a lot of confidence over the five-Test series. It is disappointing, there will be many experiences which the youngsters will learn - not too many have played Tests away from home and hopefully they can take that it into the future. "
Dhoni said there was nothing he could have done differently to make things better for his side.
"We did everything we could have done. If we went it with Rohit (Sharma), the difficulty was who to leave out. Ajinkya Rahane had scored a hundred at Lord's. Pujara bats at numnber three, Virat at four and then myself. Whatever we could have done, we tried," he said.
Fast bowler James Anderson was named England's Man of the Series. Anderson took 25 wickets and he was nominated by India coach Duncan Fletcher.
"We've fought back really well, there's been some good performances through the series. I think I'm in a good place with the ball, I think the way all four seamers have bowled in the last few Test has been hugely impressive. We wanted the nicks to carry, after the first couple of games. When you feel like you have an edge over a batsman, it does help as a bowler," he said.
Bhuvneshwar Kumar, who took 19 wickets and scored three half-centuries, was India's Man of the Series. He was nominated by England coach Peter Moores.
"It's tough but we have to look forward to the next series. We were hoping to win the series but in a five-match series it is hard to maintain your performances. The body is a bit tired but it was a good experience, playing in England, it was a great experience and I hope I do well in future. Bowlers want to bowl well here, trying to focus on line and length and I'm pleased I had success."
