Jadhav played an aggressive innings of 76-ball 120 and, along with his skipper Virat Kohli (122 off 105 balls), helped India chased down a stiff target of 351 for a three-wicket win here last night.
"What hurts the most is we had India at 60 (63) for 4. We were right in till the middle order, but went in to bowl at worst. Certainly we did not expect Jadhav to come out and play like that, credit to his 76-ball hundred. We take our hat off to him. He was striking it from ball one and gave us no chance," said Morgan about the pint-sized Pune-born batsman Jadhav's whirlwind knock.
Jadhav hit cleanly and notched up his hundred by striking 11 fours and two sixes before finishing with a brilliant 120 after joining forces with captain Kohli, who made a dazzling 122 in 105 balls, studded with five sixes and eight fours.
At times, the local boy overshadowed his famous captain with the range of his shots and the duo's 200-run partnership in 24.3 overs after India were down in the dumps lifted the hosts to 263 for 5.
Although both he and Kohli got out before finishing the job, Hardik Pandya (40 not out) and Ravichandran Ashwin (15 not out) guided India past the finish line.
Morgan, however, said that his side had done their homework on Jadhav before the game.
"We've watched the footage of the international matches that he's played in. We were not necessarily caught off guard.
We did as much as we could homework-wise," he explained.
On Kohli, who has been England's scourge from the Test series onwards, Morgan said they had their plans for him but those did not work out.
"There is always something we can do. All the plans went far off today and the balls went over head, maybe those two yards on another day, and that would have been out. And they would have been five down and you are right into them. He's a fantastic player. He (Kohli) has proven that over a long period of time," said Morgan, who was not a part of England team for the five-match Test series which India won 4-0.
