By Justin Langer Former Australia Test batsman, current Somerset captain

There is an old saying in Australia that it is often harder to get into the Australian cricket team than it is to get kicked out of it.

In other words, once a player had earned the right of selection, they were usually given a pretty good run at their position before they were moved on and replaced by another player.

Retired Warne, McGrath and Langer were an integral part of Australia's dominant Test team

One of the significant traits of Australia's dominance of world cricket over the last decade has been the continuity in selection of the Test and one-day teams.

In many respects this is a great credit to the selectors in charge and I can say without hesitation, that while the role of a selector can be a thankless task, the Australian selectors have generally shown faith in their players and followed a very consistent selection process.

Obviously there have been instances when a player has felt aggrieved and there were times in my career where I felt hard done by, but overall I believe the continuity of Australia's selection process has had a positive affect on the consistent performances of the team.

Earning promotion in the Pro40 competition and winning the Division Two championship would suggest the season has been a successful one for the Somerset County Cricket Club this year.

As the captain of the club I have no doubt that the hardest part of the job has been in selecting every team.

In Somerset's squad there are 25 players who all believe they should be in the first 11 of every game.

These changes in personnel must have some sort of destabilizing effect on the team Justin Langer on England

Unfortunately, the mathematics just doesn't add up here and, therefore, there are always guys who are disappointed at not being selected.

This said, I am sure our ability to stick with a stable team for much of the season has been one of the catalysts behind our success.

In fact, while we have welcomed the competition from the players on the fringe, I would like to think the core of the squad have enjoyed the faith we have shown in them for most of the season.

Rather than looking over their shoulders they have been able to remain focussed on what is most important; that is watching the ball or hitting the right line and length.

A consistent team has been key to Somerset's success

The only changes we have made have been forced through injury rather than as a result of poor form.

While none of the Somerset players, like the Australian players, ever take their positions for granted, they are given some room to concentrate on their role within the team rather than their position within the team.

All this said I am often surprised at the constant changes that seem to go on within the England teams.

Injuries aside, it is my belief that these changes in personnel must have some sort of destabilising effect on the team.

Throughout the one day series against West Indies and India at home I wonder how many times the same team walked out onto the park from one game to another?

In this Twenty20 World Cup it seems the same trend is continuing as England strive for the perfect formula.

606: DEBATE Have your say on 606

In cricket, I am not sure there is ever the perfect combination but I am a firm believer that if the best 11 players are selected, regardless of the format of the game, then consistent performance will generally ensue.

Australia surprisingly lost their first game of the Twenty20 World Cup to Zimbabwe, but unsurprisingly have fought back and look awesome with almost the same team that won the World Cup four or five months ago.
