Mukesh Kumar's inclusion as a replacement for Bumrah can be lethal as he will be a new face in the longest format and it’d be difficult for the opposition to read his line and length.
Ishant Sharma is one of the 11 players to play 100 Test matches for India. His experience in the longest format can be very beneficial for the team as he can get more bounce on the pitch.
Jaydev Unadkat was included in the squad against Australia in the four-match Test series but was ruled out after the first Test to play in the Ranji Trophy final. His experience can bring the first-ever WTC trophy for India.
The 35-year-old bowler has picked up 165 wickets in 54 Test matches he played so far. His ability to take wickets in the middle overs can be very helpful for the team in the WTC final. He also brings extra pace with accuracy.
The 33-year-old can swing both ways and is preparing for the upcoming season of the Indian T20 League. He might replace Bumrah in the WTC final as he has a lot of experience and his ability to swing the ball can be very useful for the team in Oval.
