In this situation where players have come in from another team with different methods its important to get YOUR ways and ideas accross as soon as possible. Even if you do things differently to what they did before its vital you have a set plan of training and playing and get those players to follow it ASAP.

Look into as many different games as possible e.g possession football where the entire point of the exercise is team work and passing etc. In a previous post where the topic was how relevant fitness was to younger players my argument was certain drills are good for work rate and team work so as long as it doesnt dominate your sessions team based shuttle runs etc CAN be fun and can get people to work together. Hopefully you will find overtime they will naturally bond better.

I hope this is of help to you. 

At the age group you are working in then the enjoyment and development should be the main priority over results. On the flip side losing especially heavily naturally drops heads and as adults we realise that there is a bigger picture but you do not think like that at 7,8 or 9 years old so being able to compete is important.

Your main aim is to get the players organised and understand their roles within the tea and their aim as a team. Although it can be argued at such a young age individual progression is important if you are going to send a team out to play a match then you do need set plans and a sense of structure for the players to understand and to follow.

I find organisation and understanding of a role within a team is excellent motivation as then if each player knows exactly what they are doing then they do not feel "lost". You will always play better teams with better players but more often and not with belief and organisation you will compete a lot better and more consistently.

Its important as their leader however dispondant the team gets yourself as well as the parents should remain up beat and confident for the sake of the players.

Belief in your self and what you are trying to get accross is also vital.

Good Luck!!

Definitely remember this, if your head drops, they will feel that they are not good enough to keep YOU interested. That's bad news for everyone.

Get them together before a session, all sat down and ask some pre prepared questions about what makes a good player and what makes players get along. Compare answers and come up with 2 or 3 ground rules, something you can remind them of like 'Always think for your team' or 'if you knock em down, pick em up' little catchy soundbites they will remember.

You can then remind them of rule '1' or rule '3' when something goes wrong in training. The idea is that they will bond with unfamiliar players by sharing ideas and realising they aren't that different.

Does that sound like it might be appropriate to your situation?
