Former England captain turned cricket analyst. Michael Vaughan. has questioned the overall fitness of West Indies all-rounder Andre Russell, despite the player’s fair start to the Indian Premier League (IPL) season.

In the second game of the campaign for the Kolkatta Knight Riders, Russell cleaned up the Mumbai Indians' tail for career-best figures of 5-15.  In the same match, however, the player was unable to finish the job with the bat as the Knight Riders slumped to a dramatic 10-run defeat as Russell added 9 from 15.

Vaughan pointed to the batsman’s work in the field and running between the crease as evidence the big hitter is not quite at his best.

“You got a player like Andre Russell, who has been a superstar, but on the field, when the ball is coming to him, he is always using his feet. He is obviously someone who cannot go down. It’s a very clever and careful aspect which Eoin Morgan will have to manage,” Vaughan told Cricbuzz.

“When he (Andre Russell) is at his best, he is great. But when you see him on the field, and when is bowling, he appears to be struggling. While batting he is not taking the twos,” he added.

“He needed to take the twos in the 19th over. Because you want him back on strike. Very difficult to manage for Brendon McCullum and Eoin Morgan.”

The Knight Riders have won 1 of their first 3 matches.
