Captaincy Controversies.

All three of England's matches in the Champions Trophy so far have contained controversy regarding the on-field powers of captains.

Here, we take a look at the incidents.

ANGELO MATHEWS (England v Sri Lanka) * SRI Lanka all-rounder Angelo Mathews was recalled by skipper Andrew Strauss after he was run out following a collision with Graham Onions in England's opening game. Mathews had turned for a second when he ran into Onions, who had held his ground, and stopped the Sri Lankan in his tracks. There was no fault on the part of Onions and while Mathews looked to be struggling to beat Joe Denly's throw to the wicketkeeper in any case, Strauss obligingly opted to recall him.

GRAEME SMITH (England v South Africa) * STRAUSS earned the ire of his counterpart Smith after turning down his request for a runner late in South Africa's failed run chase. Smith had been struggling with cramp after reaching his century but Strauss, backed by umpires Steve Davis and Tony Hill, denied the left-hander a runner on the grounds he was not injured or ill. Afterwards Smith voiced his disapproval of Strauss' decision as his side crashed out of the tournament with the 22-run defeat.

PAUL COLLINGWOOD (England v New Zealand) * THIS time it was England's opponents in the spotlight as New Zealand captain Daniel Vettori opted to allow Paul Collingwood to remain after a successful run-out appeal.

Collingwood had wandered out of his crease after a Kyle Mills delivery and a quickthinking Brendon McCullum threw down the stumps. The Black Caps appealed and Collingwood was given out by the third umpire, however, after consulting his team Vettori decided to let Collingwood stay.
