Former England batsman Geoffrey Boycott has criticised Ian Bell's recent performances.

The 33-year-old has struggled for form throughout much of 2015, having been dismissed for either a duck or one run on nine different occasions.

With that in mind, Boycott has insisted that Bell "must do more" to justify his place in the team.

"Bell is on the slide. He's averaged 20 in 23 innings since he got the hundred in Antigua [in April]. He's got to do more than that," he told BBC Sport.

Overall, Bell has averaged 42.69 from his 118 Test appearances.
