Go outta town for a few days and you miss a scrumptious thread such as this! :D
Asif_k, nowhere did I imply that "Mr. Brown has let his team down and his loyalities are not with the Namibian team but with the English Team just because he offered some suggestions to the English."
I am not one to proclaim where Brown's loyalties lie exclusively, it's very human to support your birthplace in a competition even if you're now on another's think tank. Nonehtless, as a coach of a team you're supposed to iron out the discrepancies of your own unit and egg on those placed in your supervision until the very end.
Let's take a simplistic approah by neutralizing specific names (countries & players):
Team A- the team you once played for.
Team B- the team you are now in charge of, on professional contract.
Team C, D etc- other teams.
Now if teams A-D are grouped together in a pool, you, as the coach of Team B are required to support, work out and develop your team's players' games and approaches until the very end (i.e are knocked out of the competition, arrived home or contract terminates).
The authorities that signed you would not see it favorable at all if you start not only supporting Team A (a team you are competing against to progress to the next round), but giving it tips and backing it to go all the way. That too publicly! That would hardly be the kind of attitude players would derive inspiration from. This would reflect even more negatively if yours is a team playing in its first major tournament and still has games to go!
To make it even simpler, suppose England was playing Australia and the West Indies (for example) in a tournament, and you were still the Namibian coach but are not part of the tournament in any way. Now even though you're under contract with the Namibian board, supporting the Poms would be relatively acceptable as it doesn't affect the team you have been signed to supervise in any way.
Your job was to try to improve and inspire the team you've been signed to, and since that team is not playing in xyz tournament, you are not breaching professional conduct by supporting or helping any other. As opposed to the above scenario.
