Shine (left) casts an eye over Plunkett's bowling action

"I think Shiney has been the best bowling coach I've had so far," Plunkett, 21, said in his BBC blog.

"He and Troy Cooley are very similar. Shiney gives you the opportunity to pick and choose what you want to do.

"I've changed my action a lot and he believes I've got to the stage where my action is completed."

Cooley, who was seen as a key to England's Ashes triumph in 2005, switched sides before the recent series.

He worked with Plunkett before he broke into the England side to remodel his action, aiming to make him less prone to injury.

I believe I've got the talent and enough skills to adapt to these pitches Liam Plunkett

After trailing the England Test side around Australia this winter without seeing action, Plunkett was a surprise success during the one-day series triumph, taking 12 wickets at 23.00 in six games.

Plunkett believes he will have to adapt to a new challenge during the World Cup, as conditions in the West Indies are likely to be different to Australia.

England found out on Friday, in a five-wicket warm-up defeat to their Ashes rivals in St Vincent, how important variation will be for pace bowlers.

"The off-cutters and leg-cutters that Nathan Bracken and Stuart Clark mixed in were the main reason they won and we have to try and do the same," he said.

"The wickets are different - I got my wickets in Australia through swing.

"Here I'm probably not going to get that but I believe I've got the talent and enough skills to adapt to these pitches."

Plunkett insists he is not certain of his inclusion for England's opening World Cup match, against New Zealand in St Lucia on Friday.

But Jon Lewis's struggles against Australia make it look likely Plunkett will partner James Anderson with the new ball.

England are likely to keep a close eye on Wednesday's game between Canada and Kenya at the same ground to work out whether to stick with two spinners in Jamie Dalrymple and Monty Panesar.

If they do so, Sajid Mahmood would probably be the other seamer to miss out.
