Football: play out of defense

Team keep getting thrashed every week - where to start? Having been the sole coach/manager of a little league team for the past two years, this year I lost all my senior players. I was therefore presented with 10 brand new lads, some of whom have never played competitive football. We are 8 games in and my lads are getting thrashed every week. The main problems are that they cannot get the ball out of their half, positions are usually a mess, finishing and chance creation are non-existent, and they don't apply any pressure or are unable to tackle. The main problems are keeping the ball as a team, getting it in the opponents half and staying there, and creating/finishing chances. I only have 1 and a half hours a week with them. I don't really know what to do, and I'm a little desperate. Does anybody have any advice? Thanks for literally anything.

I took over a under 8s team 2 years ago unfortunately soccer is not my game and I did as there was no other option other than to fold. Im a good coach in terms of developing a good team (discipline, teamwork , sportsmanship fun etc) but I think my lack of knowledge about the game is holding the team back . I have a 12 players who are about to move up to the under 10s level , they skill level ranges from timid to very skilled, I try to give each player equal time and the lower skilled players are improving (just not at the same pace as the opposition). Unfortunately the opposition we face seem to be light years ahead in terms of playing a scheme and we are often found out during games (i have used a basic zone defense to try and stop the team becoming ball magnets). I think its a mixture of me insisting all players get equal playing time and the fact I dont know enough about the game to be able to coach an effective scheme and to react to opposition schemes. They are good kids and I want to give them a taste of success (you can only say it was bad luck so many times) but cant seem to get our club to take it to the next level. The drills on sportsplan are helpful but a lot of drills are too complicated for the kids age or can simply go wrong very quickly in reality. We dont get thrashed in games but we cant seem to eke out a draws or wins (I know its not all about winning but try explaining that to the kids when they lose on a regular basis)Any suggestions

where on the field can I play a slow player

I have a player who can throw the ball in to near post or center of the net on most fields. We have some of our better guys in the air push up and crash on these plays, but I don't feel that we are taking full advantage of this weapon, in terms of converting these opportunities into goals. Does anyone have any suggestions in terms of where to target throwing the ball or where to position people that has resulted in a high level of success with a long throw-in player on their team?

I have a U12 girls that play8v8 with ofsides.Often times they want to hang on the 18 and wait for the attack. Despite practice. It seems some prior coaches that have coached at the varsity level feel that keeping your back line in a V formation with the center toward the goal is the best. To me having a line pressing will allow the wings and mid to get back and help. Keeping the defense back I think is bad medicine as well as creating space in between the center back and mid fielder. Allows the attack to then pass between defenders and to space. No offside advantage either. What is right. I have been able to get them to play up at least but the v formation seems to cause the advantage to the attacker. Are the higher up coaches wrong or are they trying to implement a tactic that works better with 11v11?
