hi everyone i manage a 7 a side team, we are a new u10 team and started playing league games in january, one thing ive noticed in games is my 3 midfielders and striker just give up and dont chase back when we lose the ball which results in being outnumbered at the back, any tips to help with this problem as ive tried to get across to them that we need to get back and help but its still happening. thanks
