It was a total team effort through which we won the 2011 wc. Almost everyone contributed when the team required the most with some consistent match winning performers throughout the tournament like Yuvi , Sachin, Sehwag, Gambhir (can't praise all individually, otherwise it will become a very long post )
Even see At Suresh Raina stats 4 Matches only 74 runs but scored crucial 36*against pak in semifinal where probably that made the difference at the end. Our bowlers Zaheer khan, Ashish Netra, Harbhajan, Munaf Patel did really well and Whenever Chawla and Ashwin got oppurtunites, they performed.
Regarding MSD he didn't had a great tournament with the bat in the league stages, but he stepped up and scored crucial 91*and formed very crucial partnership with Gambhir who also scored really well made 97 in the finals when it required the most unlike what the team management /captain did with him in 2019 wc semifinal by taking worst decision by sending him at no. 7
At last credit also goes to the coaching staff of that team ie. Garry Kirsten and Co.
