India suffered a shock loss to Sri Lanka in the group stage before overwhelming Bangladesh in the semis and their captain Virat Kohli has been impressed by Pakistan's resurgence.

"The turnaround has been magnificent," Kohli said.

"Obviously, if you reach the finals you have to play some good cricket and credit to them, they've turned around things for themselves really well.

"The belief just showed on the field the way they played together as a team and regardless of who you play in the finals, it's always going to be challenging because once you start thinking that it's a big game, then your mindset changes."

India, who beat Pakistan by five runs in the Twenty20 final 10 years ago, have been lifted by the outstanding batting form of Kohli, Shikhar Dhawan and Rohit Sharma.

"What we are going to try to do is repeat the similar sort of cricket that we have played so far, knowing the strengths and weaknesses they have," Kohli said.

"I don't think we need to look too far away from what we are doing as a group, focus on our skills and our abilities and believe in ourselves on that particular day."

One of the most unpredictable sides in world sport, Pakistan were the lowest-ranked side going into the tournament and produced a shambolic performance in their heavy opening defeat by India.

As they have done many times before, however, Pakistan suddenly found their form with wins over top-ranked South Africa and Sri Lanka before delivering an outstanding all-round display to stun previously unbeaten hosts England in the semi-finals.

Pakistan's rejuvenation has been built around the runs of opener Fakhar Zaman and the experienced Azhar Ali while Hasan Ali and Junaid Khan stepped up to compensate for the absence of Amir who is expected to be fit for the final.

Their captain Sarfraz Ahmed said they had quickly forgotten the opening loss to India and simply focused on the next game in their bid to win the Champions Trophy for the first time.

"After the India match, we just motivated the guys," he said.

"Don't worry about the India match. This is gone. If we play good cricket, definitely we will win this tournament."
