Squad: 
 
* Shreyas Iyer is Injured and will not be a part of this IPL 2021, Replacement is yet to be announced
Strengths:
1. Bowling Line-Up: Delhi has the best bowling line-up among all 8 Franchises. 
yeah, they have a better bowling line-up than Mumbai Indians also. Last time Delhi lost against MI, not because of their bowling but because of their poor batting. 
With the likes of Rabada, Nortje, Ishant, Ashwin, Umesh, Woakes, Stoinis, Axar, and Amit they have all the boxes tick in their bowling Department, As of now it is looking Rabada-Nortje will start with Ashwin and Axar and one between Amit Mishra and Ishant Sharma will play with respect to the pitch, They also have some overs of Marcus Stoinis too, don't forget last year he defended 1 run from 3 balls, They also have the option of Chris Woakes as a backup of Rabad-Nortje and in terms of Indian Backup, they have Umesh Yadav, Now you just examine the quality of their bowling line-up, that their backup options are also the first-choice players for their respective countries. 
This bowling line-up has the ability to even defend 120 runs also, I must say that this season also DC is going to qualify for playoffs and one of the main reasons for it will be their bowling.
2. Threatening Batting Lineup: I mean just look at their Batting Lineup- Prithvi Shaw, Shikhar Dhawan, Rishab Pant, Ajinkya Rahane, Steven Smith, Sam Billings, Shimron Hetmyer, Marcus Stoinis, and don't forget they have good Indian backup's in form of Lalit Yadav and Vishnu Vinod, And Axar and Ashwin too can bat, it's really threatening for the other 7 teams in the tournament, and it's after the exclusion of Their one of the main batsman Shreyas Iyer.
On their day this batting lineup is capable of making 250 runs also, They just had to be a little careful in the middle overs by not losing wickets at regular intervals, and for this purpose this year they can play one Among Ajinkya Rahane and Steve Smith to act as a glue in this Aggressive batting lineup. 
Their all boxes are ticked in their batting department too, they just have to decide between who will play among Hetmyer, Billings, and Steve Smith, it's tough because all three of them are Match winners.
3. Experience: Surprised, to see experience mentioned as a strength here, but guess what they have players like Rahane, Ashwin, Smith who are the former captains in IPL, and they have Ricky Ponting as their Coach, Just Imagine the god level strategies which these 4 clever minds are going to make along with young Rishab Pant. 
Weakness:
1.Unavailability of Shreyas Iyer: According to me Delhi has only one weakness in this season, and that is the unavailability of Shreyas Iyer, Delhi might not miss Shreyas Iyer the captain very much but they are surely going to miss Shreyas Iyer the Batsman.
His unavailability has created a vacuum in the playing XI, If they start with Rahane in playing XI For Iyer, then they can play Billings or Hetmyer at 5, but if Rahane doesn't perform then they will be in deep trouble because they don't have any other reputed Indian replacement, and if they go with Steve Smith at 3 then they can't play Hetmyer or Billings at No 5, or if they want to play Hetmyer or Billings at No 5 along with Steve Smith at No 3, then they have to break their strength that is Duo of Rabada and Nortje, by replacing one with Umesh Yadav, but this seems unrealistic, All this mess has created just because of unavailability of Shreyas Iyer the batsman. 
Probable Playing XI:
1. Shikhar Dhawan
2. Prithvi Shaw
3. Ajinkya Rahane
4. Rishab Pant (c) (wk)
5. Shimron Hetmyer
6. Marcus Stoinis
7. Axar Patel
8. R Ashwin
9. Kagiso Rabada
10. Anrich Nortje
11. Ishant Sharma/Amit Mishra (depends on the pitch)
Three Key Players According To Me:
1. Rishab Pant: 
The Future captain of Team India, The center of attraction of the current international cricket -Rishab Pant will going to be the spinal cord of this team, This time he is not only the batsman but he is the Captain also, It will be interesting to see how he leads, but in kind of form he is now, I won't be surprised if he wins DC their maiden IPL title.
2. Marcus Stoinis:
He was The MVP for DC last year, Scored Tons of Runs with the Bat coming down the order, showed that he can Open too, Took wickets in the crucial moments of the match, was being able to defend 1 run in the last 3 balls of the match, Overall he was the reason of Success for DC last year, And this year also the success of DC will be equivalent to his success as an allrounder
3. Kagiso Rabada: 
Purple cap winner of last year, This South African fast bowler can turn the match with his pace, In my book, he is more useful and better in IPL, than Jasprit Burah and Jofra Archer, He can take wickets at any time in Power-Play, in Middle Overs and in Death overs too, So if this year DC wants to accomplish their dream of lifting their maiden IPL cup, then Rabada has to make Kabada of the batsman's of other teams.
Tournament Prediction:
Their Team looks very strong in papers in this season too, They got power-packed Batting, an Excellent Bowling Lineup, All they have to see is their weakness (mentioned above), and if they want to overcome their weakness then Ajinkya Rahane needs to fire this season, And if he starts getting runs, then you will see this team playing finals once again, but if he can't then it's going to be very tough for them to overcome from it, don't forget they don't have the replacement of Prithvi Shaw too this season if Rahane plays at 3. 
Along with this, one area which they also need to address is their consistency, they start very well but in the middle of the tournament they lose momentum, This season they have to make sure that it doesn't repeat, if they start well then they can't lose their winning momentum.
This season Rishab Pant will lead this franchise, And right now in the kind of form he is I can say that the luck is with him, And if he able continues his batting form in IPL too, then I can surely say they will not only qualify for playoffs but they will play Finals too, Sometimes the stars of a player helps the team too, And this season I'm seeing this happening with Rishab Pant as this coming decade is completely his now.
My prediction is That This year Delhi Capitals will lift their maiden IPL title.
