While MS made his debut late in 2004, Raina broke into the Indian side in mid 2005. Soon MS cemented his place in all three formats, but Raina became a regular in limited overs arena only around 2008-09. Together, they formed a dynamic finishing duo batting at No. 5/ No. 6, and also a damage control pair when the top order would fall quickly. Another interesting piece of trivia that binds them together, is regarding their respective last test matches. In 2014, when Dhoni played his last test, he informed Raina about it the night before, and also gave him his test jersey. Raina would go on to play the next test, which would later become his last as well !
Dhoni took Indian cricket to the next level. Under his regime, India won T20 World Cup (2007), 50 over World Cup (2011), Champions Trophy (2013), and reached number 1 rank in test cricket (2010). Indian fielding improved drastically during this period, and much of credit goes to him. On a personal front, he made some stellar contributions with the bat, some of them being 148 against Pakistan (2005), 183* against Srilanka (2005), 91* against Srilanka (2011 World Cup), 113 vs Pakistan (2012), 224 against Australia in a test match (2013), 139 vs Australia (2013), and 134 vs England (2017). Apart from his unorthodox yet effective batting style, his work behind the stumps was just out of this world. He is, still, the best wicketkeeper among the current lot. He had a lean World Cup in 2019, did not play any cricket since then, and his retirement news comes more or less on expected lines.
Raina, on the other hand, was the best T20 player in India at one point. His career highlights include a 120 on test debut against Sri Lanka (2010), 101 against South Africa (2010 T20 World Cup) making him the first Indian player to hit a century in T20 internationals, crucial 30s against Australia and Pakistan in quarter final and semi final respectively in 2011 World Cup, 100 against England (2014), and a match winning 110 against Zimbabwe (2015 World Cup). Although he wasn’t considered the best against the moving ball on bowler friendly pitches, all of his seven international hundreds came outside of India. A great fielder, also used to chip in with some handy offspin, he truly was a great asset to the Indian side over the years.
Having said that, we don’t have to wait too long to see them in action together, as both of them will play for CSK in IPL starting next month.
