Top British rugby commentator Stuart Barnes has warned the Lions against picking Sam Warburton as captain for the 10-match New Zealand tour.
An expected 38-man squad is named on Thursday and despite a leg injury, and having been dropped as Wales captain, Warburton is favoured to retain the leadership job he had in Australia four years ago.
Barnes, writing in The Times, said Warburton had the wrong sort of game for the three-test series, where Warren Gatland's tourists would need ball carrying forwards rather than a tackling dynamo. He did not specify his captaincy pick.
Barnes wrote: "Warburton is a fine player. A good man. These are not the issues. It is the nature of his game.
"Four years ago I suggested that the injury he suffered during his heroic effort in the second test defeat by Australia in Melbourne would benefit the Lions in the decider, despite the flanker undoubtedly being the outstanding player on the pitch.
